The article is devoted to the development of a mathematical model of the complex “ ground base-foundation-construction-external influences” taking into account the cyclic technogenic vibrational loads. The mathematical model is used in automated systems of geotechnical monitoring. The coefficients for a qualitative separation of the types of vibrational technological impact and its quantitative presentation are introduced into the model. These coefficients provide the implementation of the criteria for safe and efficient operation of the foundation and the structure as a whole. At the computer modeling, the dependence of the strength parameters in the complex “ground base-foundation-construction-external influences” was evaluated. It is established that the calculation using the developed mathematical model allows increasing the sensitivity to early detection of a decrease in the strength characteristics of the foundation structure by an average of 24%.
