地下水渗流对基坑工程稳定性影响研究进展

Research Progress on the Influence of Groundwater Seepage on the Stability of Foundation Pit Engineering

随着城市化进程的不断发展,基坑工程成为城市建设不可或缺的部分,而地下水渗流对基坑稳定性的影响也受到广泛关注。首先总结了渗透理论的发展历史,从理论的不断革新来表明人们对渗透问题理解的进步。随后分别从理论分析法与实验分析法出发,阐述地下水渗流对基坑工程问题的研究进展。最后总结以上方面得出,基坑工程渗流问题应多关注成层土各向异性,固结强度动态变化与时间效应,非稳定流理论的建立与应用等方面。

The foundation pit engineering has become an indispensable part of urban construction with the continuous development of ur‐banization.And the influence of groundwater seepage on foundation pit stability has also been widely concerned.In the beginning,introduced the development of infiltration theory,showing the progress of people’s understanding of infiltration issues.Then,the research progress of groundwater seepage on foundation pit engineering was illustrated from theoretical and experimental methods.Finally,it is concluded that the seepage problem of foundation pit engineering should pay more attention to the anisotropy of layered soil,the dynamic change of consolida‐tion strength and time effect,the establishment and application of unsteady flow theory.
