摘要

运用工程系统分析方法对浙江某基坑工程进行了稳定性评价分析

通过工程系统二元机理、机理网络路径和结构矩阵计算分析

形成了实际工程系统耦合矩阵.结合工程实践和系统耦合矩阵

分析了变量间及系统变量间的相互影响

并对工程系统稳定性进行了具体的评价分析.经过系统耦合分析发现

基坑开挖深度、支护桩变形、周边地面沉降和土压力对基坑系统的稳定性影响较为显著

工程中可采取优化这些系统变量的措施

达到改善基坑稳定性的目的.工程系统耦合分析方法对合理的基坑支护优化设计具有现实意义.

Abstract

A foundation pit stability of a foundation pit engineering in Zhejiang

China

is evaluated and analyzed with the engineering system analyzing method. The engineering system fully-coupled matrix is established via calculating system binary mechanism

mechanism network paths

and binary mechanism matrix. Combining engineering practice with system fully-coupled matrix

the interactions among the variables in practice and system are discussed

furthermore the engineering system stability is evaluated. According to the fully-coupled system analysis

it is found that the foundation pit excavation depth

retaining pile deformation

surrounding earth settlement and soil pressure affect obviously the stability of foundation pit system. Thus the optimized system variables can be taken to improve foundation pit stability.
