    The present paper shows the way in which by field tests such as light and standard dynamic penetrations, the effects of a deep excavation on the nearby constructions could be quantified. The consolidation works could be design taking into account the interpretation of the test result

    The paper presents the analysis of foundations conditions under static and seismic loads for a wind farm located in the Eastern part of Romania. From lithological point of view, the location is characterized by a soft cohesive strata alternation over 40m deep. Some design considerations for obtaining the most economical foundation options are discussed. By taking into account the static and seismic conditions, the soil – structure interaction (S.S.I.) is also revealed together with conclusions on the aeolian towers’ foundations solutions

    In the eastern part of the Romanian territory there are wind intensity conditions for some big eolian power units. From lithological point of view, the mentioned area is characterized by a loessial stratum of 3 up to over 20m deep which covers green shale rocks. The paper presents the designing consideration discussed in order to obtain the most economical foundation option. The corresponding calculus conclusions about the soil-structure interactions in seismic conditions are also revealed

    The inhabitants of a village situated in the southern side of Romania have sued juridical action the local mining company considering that the coal quarry and the new sterile dump situated near up the locality, are the main cause of the civil buildings damages. In order to establish the true causes of damages occurred in the village area a number of 129 buildings has been monitorised and 19 geotechnical drillings were dug surveying the ground structure. Inclinometric tests have been performed for one year in 15 boreholes spread on several profiles. A global stability analysis was performed as well. Our study pointed out that, despite the appearances, the damages arc due to local previous landslides and inadequate foundation solutions

    The paper presents the analysis of a road embankment with variable height (between 4-10m) placed at Iassy, Romania, in the first year of service. It’s about access ledge at a bridge with total length of about 300m. At this time the embankment presents longitudinal cracks parallel with road axle, lateral knobs corresponding to each compacted layer, infiltrations through the backfill from the top (faulty pluvial system) and from the bottom (flooded foundation soil without drainage system). Foundation soil is a metastable clay. Triaxial tests type CKoD on stress loading paths have shown that this soil is sensitive to moistening at shear stresses. The embankment is made also from a clay unusually used for such type of structures and several geosynthetic layers. At the top there is an elastic pavement. The footwalks over the embankment are from reinforced concrete and are bracket assembled. The slopes are 10:1 and are air-placed concreted. The finite element model has taken into account various hypothesis: 1. Model with the soils in natural state, 2. Model with foundation soil in flooded state, 3. Model with foundation soil in flooded state and different artificial consolidation on embankment width. The article presents stresses, strains, and also the stability analysis in seismic conditions imposed by P100-2006. It also presents a prognosis of general state under seismic conditions, analysed limit state of stability and also limit state of bearing capacity of foundation soil
