摘要
在总结地下微承压水对工程危害的基础上,分析了微承压水渗流对基坑工程的影响,尤其是支护上被动土压力的影响。利用有限元程序计算了考虑基坑中微承压水作用下的整体稳定性,绘制微承压水影响下基坑周边和下部土质中的渗流场,结合工程实例进行分析,得到了微承压水影响下的基坑稳定分析的量化结果。从而为工程实践提供了一定的理论依据。
Based on summarizing harms of micro-artesian to construction, the authors analyzed stability of foundation under the influence of micro-artesian and confined water seepage , especially the passive earth pressure on the bracing. Through analyzing the total stability of foundation soil and plotting the field of seepage flow around the foundation using finite element program, some quantification results combined with practice can be obtained, which can provide theoretical evidence for practical constructions.
