某地铁车站深基坑土体滑移原因分析及加固措施

随着城市轨道交通建设的发展，城市深基坑工程越来越多。深基坑工程风险源众多，需要将风险控制在可控范围之内。针对某地铁深基坑土体纵向滑坡，分析了产生纵向滑移的原因和应采用的加固措施，并提出了需要注意暴雨、冻融的不利影响和开挖时的动态监测。

Cause Analysis and Reinforcement Measures for Soilmass Sliding at Deep Foundation Pit in a Subway Station

As the development of urban rail transit, there are more and more deed foundation pit engineering in cities. For such works, the risk resources are numerous and required to be controlled within a certain range. In relation to a longitudinal sliding of soilmass at deep foundation pit for a subway, the causes and the essential reinforcement measures were analyzed, and the suggestions include that the adverse influence of rainstorm, freezing and thawing need be concerned, and also dynamic monitoring in excavation is proposed.
