The use of modern soil models is impossible without carrying out a full range of laboratory tests required to determine the initial soil parameters and their further verification. The correctness of these aspects has a significant impact on the final result of numerical modeling. This paper gives a brief overview of the investigated soil models, presents the results of their verification using the geology of St. Petersburg, and compares the results of their verification on the example of the geology of St. Petersburg. Furthermore, the calculation results are compared using verified soil models (Hardening Soil, Hardening Soil Small and Generalized Hardening Soil) and unverified soil models (Hardening Soil) with geotechnical monitoring data. As an example, the authors describe a method intended for modeling the upheaval of the base of buildings of the surrounding development when using Fundex bored piles on an adjacent site.
