Construction and further operation of buildings and engineering structures in karst-hazardous areas in most cases is connected with possible man-made increase of geodynamic manifestations of karst processes. As a result of this, in the soil foundations of engineering structures, the appearance of decompression zones with reduced load capacity is possible. In some cases, an active manifestation of karst-suffusion processes is possible. In this case, the probability of unacceptable deformations of the soil base with a further destruction of the foundation and the structure itself is high. In this regard, the development and application of new methods of geotechnical monitoring, which will highlight the hidden manifestations of pre-crisis situations based on complex geophysical measurements, taking into account the relationship of the influence of natural, natural-technological and technogenic factors on the control object, is relevant.
The article describes the geotechnical model of the engineering-technical structure in the proposed control area. Examined and the substantiation of the integrated approach to solving the problems geotechnical monitoring complex "soil base - foundation - building" in order to identify the initial stage of destruction of the foundation by combining seismic and geoelectric control method of the geological environment. It is shown that the joint processing of heterogeneous geodynamic monitoring data will allow a more accurate description of the development of destructive processes in the complex "soil base - foundation - building". The methodology of laboratory modeling of the geotechnical system with the aim of assessing the prospects of using the seismoelectric effect in the problems of monitoring the soil base is considered. The results of laboratory studies are presented. |
