为了评估复杂环境下基坑工程施工的可行性,提出了将工程地质的场地整体稳定性分析、基坑边线附近地层稳定性分析引入基坑施工过程模拟的分析方法.通过地层分析与三维有限元计算的有机结合,对复杂环境基坑工程的施工可行性作出评估.使用上述方法对一个典型工程实例的分析,验证了地层分析结合有限元方法的可行性,说明场地稳定性分析有助于了解工程场地及其周边区域的地层情况.采用与实际情况相同的起伏岩、土层面进行计算,能更真实地模拟基坑支撑体系的实际状态,为今后复杂周边环境、复杂地质条件基坑的分析提供了一个新的思路.

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.
