沈阳厚层粘性土区地铁基坑整体滑动稳定性计算问题探讨

Discussion on Computational Problem of Complete Sliding Stability of Subway Foundation Pit in Shenyang Region with Thick-layer Cohesive Soil

以沈阳地区典型厚层粘性土区域地铁基坑工程实际为背景,针对地铁车站工程狭长基坑整体滑动稳定性计算问题,采用传统土力学方法与有限元强度折减法分别进行定量分析,得出主要影响因素及计算优化建议,供设计参考。

Taking the engineering practice of subway foundation pit in Shenyang region with typical thick-layer cohesive soil as the background,aiming at the computational problem of complete sliding stability of long foundation pit for the engineering of subway station,the quantitative analysis is made by adopting traditional soil mechanics method and finite element shear strength reduction method respectively to obtain the main influencing factors and suggestion on computational optimization,so as to provide reference for the design.
