基坑渗流与土的岩性分析

近些年来,大型的桥梁和建筑基坑深度已经越来越深,桥梁和建筑基坑占地面积也越来越大,和地下水关系也更加密切,尤其是最近一两年内,地层深处承压水对于基坑影响越来越大,地层深处承压水已经使得很多大型桥梁和建筑基坑工程由于突涌水、流土和坑底地基管涌等原因而导致了破坏,其中,百分之百十以上的大型桥梁和建筑基坑破坏都和水有着密切的关系。本文中,笔者就对基坑渗流与土的岩性进行简要的分析。

Analysis of Lithology of Soil and Seepage in Deep Foundation Pit

In recent years,large-scale foundation pit depth of buildings and bridges has become increasingly deep,floor space of buildings and bridges is also growing,the relationship with groundwater is more closer,especially in last a year or two,the influence of confined water with deep formation on foundation pit is increasing.Confined water with deep formation has made large-scale foundation pit engineering of bridges and buildings destroyed,during to water gush,flowing soil,piping in the seepage of bottom of foundation.Among these,foundation destruction of large-scale bridges and buildings are closely related to water.In this paper,Seepage in foundation pit and lithology of soil were analyzed.
