    The relevance of the research is determined by the growing demands to using volumetric geophysical methods of non/destroyed control for diagnostic of foundation bottom grounds fixed by special cementing works where the mandatory attribute is a geophysical control of the quality of strengthening in addition to the discrete measurements on samples taken in special pits and wells. The aim of the research: 1) analysis of physic/geological and technical situation on the research object with subsequent composing of physic/geological and physic/technical models for choosing the complex of modern geophysical non/destructive control technologies and methods of measurement results processing by using specialized processing complexes; 2) research of condition of technogenic fixed grounds of foundation bottom by GPR/radar and seismic methods in conditions of the long/term used object of the cultural heritage of the regional importance Β«Memorial building B. Dom AlfuzovaΒ», 1880, Taganrog. Methods of research: 1) GPR/radar survey inside and outside the building by parallel profiles laid along the walls on distance of 2,5 m from each other; 2) seismic survey by the methods: a) longitudinal profiling with many/point system of observations; b) seismo/translucency by the scheme of surface-basement with step between fluctuation receiving points 1 m and record of seismograms with the time of registration 256 ms, sampling frequency 4000 Gz and the evolvent 100 ms.Β Results. The authors have implemented the specific example of setting and resolving the tasks of the quality control of the grouting of foundation bottom using geophysical methods in conditions of long/term exploitation of buildings and structures, and namely: 1) the zone of grouting by Q/factor index on depth and as you move away from the faces of the foundation was determine by the GPR/radar survey; 2) the data on the: a) degree of grouting (K), right next to the foundation and as you move away from it at distance to 5 m; b) deformation module (Edef) of grounds near the side edges of foundation and away from them at distance to 5 m; v) distribution speed of the elastic waves into the grouting at horizontal section under foundation bottom, were obtained by seismic works. The results of research were analyzed on improvement of the complex of shallow depth geophysical methods. For this purpose the authors carried out the short review of domestic and foreign publications by shallow depth geophysics at building and archeological objects

    Relevance of the research is caused by the necessity to solve engineering geological tasks in non-destructive investigation of solidity and technical conditions of supporting walls, erected in potentially landslide dangerous areas, by express geophysical methods. The aim of the research is to estimate the informational content of the ground penetrating radar method in engineering and construction area at survey of vertical supporting wall with following processing of field observations by specialized programmes GEORADAR-ECSPERT and ATRAN. The paper highlights the limited mobility of the ultrasound and acoustic methods in which the intimate contact of transmitting and receiving sensors of seismic wave field with vertical surface of the studied object is required when measuring. This does not technically allow recording field signal in motion. Methods of the study: ground penetrating radar survey of supporting wall by radar OKO with 400 MGz antenna unit by means of moving of the latter along vertical profiles on specially installed rope skis pressing the unit to the wall with help of the wooden pole at registration and control of radargram in online mode.Β Results. The paper demonstrates the opportunities of the attributive analysis of the ground penetrating radar survey data for studying the conditions of supporting wall on landslide slope of the right bank of the Don river in Rostov-on-Don with detection and contouring by the Q-favtor attribute values the areas with relatively solid and relatively weak masonry and location of metal dowels (steel pipes) into the front and side walls body. The diagrams were interpreted on the base of the diffracted wave pattern studying method and distinctive Β«ringingΒ» in the shape of re-reflections from dotted objects. Additionally the authors have analysed the reflected signals energy in the program ATRAN. In outcome of the studies the contact of the wall with ground was explored. It can be considered relatively evenly dense. For the side wall the lower part is denser than the upper one, and for the front wall the less dense contact into range of 20-25 m from the left edge of the wall is observed

The aim of the research is to estimate the informational content of the ground penetrating radar method in engineering and construction area at survey of vertical supporting wall with following processing of field observations by specialized programmes GEORADAR-ECSPERT and ATRAN. The paper highlights the limited mobility of the ultrasound and acoustic methods in which the intimate contact of transmitting and receiving sensors of seismic wave field with vertical surface of the studied object is required when measuring. This does not technically allow recording field signal in motion. Methods of the study: ground penetrating radar survey of supporting wall by radar OKO with 400 MGz antenna unit by means of moving of the latter along vertical profiles on specially installed rope skis pressing the unit to the wall with help of the wooden pole at registration and control of radargram in online mode. Results. The paper demonstrates the opportunities of the attributive analysis of the ground penetrating radar survey data for studying the conditions of supporting wall on landslide slope of the right bank of the Don river in Rostov-on-Don with detection and contouring by the Q-favtor attribute values the areas with relatively solid and relatively weak masonry and location of metal dowels (steel pipes) into the front and side walls body. The diagrams were interpreted on the base of the diffracted wave pattern studying method and distinctive Β«ringingΒ» in the shape of re-reflections from dotted objects. Additionally the authors have analysed the reflected signals energy in the program ATRAN. In outcome of the studies the contact of the wall with ground was explored. It can be considered relatively evenly dense. For the side wall the lower part is denser than the upper one, and for the front wall the less dense contact into range of 20-25 m from the left edge of the wall is observed
