Interdisciplinary approach in evaluating the stability of a rock mass affected by slope deformations using geophysical methods

Cieľom diplomovej práce je interdisciplinárny prístup pri hodnotení stability horninového masívu zasiahnutého svahovými deformáciami s využitím geofyzikálnych metód. Pre dosiahnutie cieľa hodnotím geofyzikálne merania na troch lokalitách. Na prvej lokalite bolo treba overiť inžinierskogeologické a hydrogeologické pomery územia, posúdiť príčiny vzniku lokálneho zosuvu a navrhnúť spôsob sanácie trasy plynovodu pre budúce uloženie plynového potrubia v súčasnej pripravovanej trase - pracovnom pruhu. Na lokalite nebolo možné realizovať vrtné práce a príprava inžinierskogeologického profilu pre stabilitný výpočet v programe GEO5 bola viac menej založená na výsledkoch elektrickej odporovej tomografie, dynamickej penetrácii a laboratórnych výsledkov. Na druhej lokalite došlo k havarijnej situácii, kedy bola svahovými pohybmi porušená obslužná komunikácia a rekreačné chaty na ľavom brehu vodnej nádrže Dolnohodrušského tajchu. Úlohou bolo overenie inžinierskogeologických a hydrogeologických pomerov územia, posúdiť príčiny vzniku lokálneho zosuvu a navrhnúť spôsob sanácie. Na tejto lokalite boli realizované vrtné práce, laboratórne práce, geofyzikálne práce, výpočet stability a návrh sanácie. Na tretej lokalite boli realizované opakované geofyzikálne merania metódami elektrickej odporovej tomografie (ERT), spontánnej polarizácie (SP), dipólového elektromagnetického profilovania (DEMP), elektromagnetického žiarenia (EMR) a jedno merania georadarom. V tejto kapitole sa venujem monitoringu svahovej deformácii na základe opakovaných geofyzikálnych meraní.The aim of the thesis is an interdisciplinary approach in the evaluation of the stability of a rock massif affected by slope deformations using geophysical methods. To achieve the goal, I am evaluating geophysical measurements at three locations. At the first location, it was necessary to verify the engineering geological and hydrogeological conditions of the area, assess the causes of the local landslide and propose a method of rehabilitation of the gas pipeline route for the future laying of the gas pipeline in the currently prepared route - the working lane. Drilling work could not be carried out on the site, and the preparation of the engineering geological profile for the stability calculation in the GEO5 program was more or less based on the results of electrical resistivity tomography, dynamic penetration and laboratory results. In the second location, there was an emergency situation, when the service road and recreational huts on the left bank of water reservoir Dolná Hodruša were broken by slope movements. The task was to verify the engineering geological and hydrogeological conditions of the territory, investigate the causes of the local landslide and to propose a method of rehabilitation. Drilling work, laboratory work, geophysical work, stability calculation and rehabilitation design were carried out at this location. At the third location, repeated geophysical measurements were carried out using electrical resistivity tomography (ERT), spontaneous polarization (SP), dipole electromagnetic profiling (DEMP), electromagnetic radiation (EMR) and one GPR measurement. In this chapter, I deal with the monitoring of slope deformation based on repeated geophysical measurements.224 - Katedra geotechniky a podzemního stavitelstvívýborn

Umbrisols at Lower Altitudes, Case Study from Borská lowland (Slovakia)

Umbrisols generally develop in a cool and humid climate. Therefore, occurrence of these soils in the Borská lowland of southwestern Slovakia is very uncommon, and this inspired the aim of this paper: Analysis of the natural conditions suitable for Umbrisol development. Umbrisols in the Borská lowland developed from aeolian quartz sands accumulated on Neogenne marine clay sediments. Their occurrence is connected with the groundwater table relatively close to the ground surface and this particularly determines Umbrisol genesis in this area. Sufficient input via organic matter is an important factor for formation of the umbric horizon, and only the rich herbaceous undergrowth of the prevailing planted pine and mixed pine-oak forests is capable of providing it. A growth of diep-rooted grass is closely connected with higher soil moisture content, and quite moist areas occur in the deeper inter-dunes depressions. Constant soil moisture in these sites is facilitated by water capillary elevation. While Umbrisols are transformed to Arenosols at increased altitude, they can be transformed to Gleysols in deep depressions. Herein, induced polarization provided suitable geophysical method for detection of arenic Umbrisol inclusions. Sharp transformation of the humus layer to dry non-polarized aeolian quartz sands enabled the surface horizon to be distinguished by induced polarizatio

A case study for identification of organic-silt bottom sediments in an artificial lake formed in gravel alluvium in the geotourism locality of Slnecne Jazera in Senec (Bratislava, Slovakia)

This case study aims to identify the cubic capacity and geometry of the geological body of silt-organic sediments in the environment of a former gravel pit situated in a drainless depression of the alluvium of the Cierna voda River. It is located in the well-known geotourism locality of Slneene Jazera in Senec, in the SW of Slovakia. To identify the body, electrical resistivity tomography was combined with the use of sonar. The research shows that this approach is appropriate for a number of activities that are subjects of engineering-geological investigations. The cubic capacity and geometry of specific aqueous engineering-geological environments must be determined in connection with the need for the management, control, quantification and extraction of selected sedimentary bodies. In addition, the management of sustainable development of reservoirs, sedimentation basins, industrial ponds, settling pits and natural pools for recreation (the subject of the case study) is important to control the limit amounts of sediments in such environments. The results of this study may be applied in analogous engineering-geological conditions. The drainless depression Slneene Jazera contained a body of silt-organic sediments amounting to 23 000 m(3) (41 Olympic-size pools of 25 m x 12.5 m x 1.8 m). The maximum thickness of the bottom sediments was about 6.3 m on the alluvium with an articulated morphology owing to the submerged digging of gravel. The proposed approach improved the control of extraction of the sedimentary body and optimized the engineering-geological conditions in this geotourism locality.Web of Science53228227

Investigation of a hazardous uncontrolled dumpsite in an oxbow lake of the Nitra River for pollution potential: a case study

This paper deals with the engineering-geological investigation of uncontrolled dumpsites that are abundant in post-communist countries. The sites may be redeveloped in an optimal manner by using the applied methodology of engineering-geological investigations. The research tool is a case study dealing with hazardous uncontrolled dumpsites chemically contaminated by various substances, particularly carcinogenic chromium. The dumpsite is located in the alluvial sediments of an oxbow lake of the Nitra River in the Slovak Republic. The hazard is seen in the fact that the alluvial sediments are permeable and thus the contamination may spread easily. At the same time, it is located near a river, which makes the hazard greater. Apart from the risk of contamination, another risk is related to the methane generated by the dumpsite and thus the risk of self-ignition. In order to identify the uncontrolled dumpsite body, the research was grounded in the different physical properties of the diverse geological environments. Quasi-homogenous blocks of the dumpsite body and its alluvial surroundings were well identified by using the combined three geophysical methods, namely dipole electromagnetic profiling (DEMP), electrical resistance tomography (ERT) and spontaneous polarization (SP). In order to eliminate the risk of contamination spread, redevelopment measures for the uncontrolled dumpsite in the form of sealing walls and surface sealing foil were proposed. A system of methane drainage boreholes was proposed to eliminate the risk of self-ignition. The methodology in this case study is well applicable for other uncontrolled dumpsites, which is an important outcome of the study.Web of Science1921art. no. 4

Surface geophysical methods used to verify the karst geological structure in the built-up area: A case study of specific engineering-geological conditions

This article presents a research study of complex limestone karst engineering-geological conditions in the municipality Valaska near Banska Bystrica in Slovakia. The aim of the study is to demonstrate the impossibility of spatial identification of cave spaces using surface geophysical methods due to the specific engineering-geological conditions of a thick surface layer of anthropogenic fill containing highly heterogeneous anthropogenic material. Its maximum thickness is 3 m. Another specificific condition of the study area is its location in the built-up area, due to which the applicability of geophysical methods was limited. The article contains methodological recommendations to be used in analogous geological conditions with karst structures topped with anthropogenic fill, which complicates the identification of cave spaces. The recommended solution herein is the identification of the cave system using underground mapping of the karst and its projection onto the surface for which surface geophysical methods have been combined.Web of Science9551770176

Physical properties of Hradište border fault (Turiec Basin, Western Carpathians, Slovakia) inferred by multidisciplinary geophysical approach

International audienceThe Hradište border fault zone has played an important role in the development of the tectonic contact of the Cenozoic sediments of the Turiec Basin with the Malá Fatra Mountains crystalline basement. Seismic, geoelectric, radiometric, gravimetric, magnetometric and ground penetrating radar measurements were used to study the physical properties and determine the exact position and inclination of this fault zone down to a depth of up to 40 m. The Hradište border fault zone represents an almost vertical physical boundary characterized by decreasing seismic velocity (from 3.0 km.s−1 to 2.2 km.s−1) and decreasing electrical resistivity (500 to 150 Ω.m) when passing from the basement west of the fault to sediments to its east. It corresponds also to a compact segment of the lowest volume activity of radon 222Rn values in soil air (8 kBq.m−3 on average) and maximum horizontal gravity gradient (−0.0076 mGal.m−1). The discovery of this anomalous zone also helps us to distinguish two different anomalous blocks. The block west of the fault represents the orthogneisses of the Tatric crystalline complex belonging to the Malá Fatra Mountains. The eastern block is built-up by the Bystrička Member Pliocene sediments of the Turiec Basin. Our study serves as a case study for geophysical research on faults in different tectonic units of the Western Carpathians and other similar orogens
