Abstract:

A compound method which includes integral site stability analysis, stratum stability analysis of foundation pit boundary and 3D finite elements is proposed to evaluate the feasibility of deep foundation pit project in complex environment. A typical foundation pit project is used to evaluate the feasibility of the compound method. The analysis results indicate that the ground stability analysis is useful to understand the stratum situation of project site and adjacent area. In 3D finite elements, undulate stratum can simulate the supporting system more accurately. The compound method brings a new analysis method for foundation pit project in complex environment and complex geological conditions.

Key words: complex environment, deep foundation pit, stratum stability analysis, 3D finite elements
