Abstract: The description of the unique object of research is given including the methodology of conducting engineering and geological surveys by methods of mechanical core drilling of 36 wells with a depth of 20 m to 35 m and static sensing using the PTM-M electromechanical logging device complete with a type II Peak strain gauge probe. The main technical means for testing soils in the field and processing their results are given. A geological and lithological section along the axis of the bridge crossing on bank supports with engineering-geological elements and discovered oolitic limestones is given, which, under the influence of groundwater being slightly acidic solutions penetrating into the carbonate thickness through cracks dissolve, forming funnels, wells, sinkholes, caves, underground channels and other manifestations of karst. The results of determining the physical and mechanical characteristics of soils are presented. As a result, it was found that the soil massif is composed of upper quaternary deposits, including loams, sandy loams, sands, crushed stone, gravel and pebble soils, the physical and mechanical properties of which correspond to the normative. The presence of oolitic limestones gives the object under construction a special feature requiring additional special geological and geodetic studies of the karst zones.
