摘要：Based on the study of reconnaissance and extension engineering geological investigation data of an office building, combined with indoor geotechnical test results and parameter inversion calculation, the reasonable basic geophysical and mechanical parameters are obtained. The numerical simulation software MIDAS/GTS was used to simulate the four dangerous sections which affect the surrounding buildings. The influence of excavation of foundation pit on surrounding buildings was predicted by numerical simulation and analysis of construction site and combining with practice. Through the simulation of the construction steps of the foundation pit excavation, the calculation results were reasonable in theory, and had the main engineering significance for the foundation pit excavation.
