地铁车站异形断面基坑的变形分析与控制

Deformation Analysis and Control of an Abnormally Shaped Foundation Pit of a Subway Station

摘要: 以某地铁车站异形断面基坑工程为例，采用二维有限元法对其异形断面基坑的施工进行了模拟，重点分析了异形基坑的变形特性，以及围护桩刚度、支撑形式、土层加固、土台宽度对基坑围护桩侧向变形的影响，分析结果可为设计提供依据。

Abstract: This paper analyzes the construction of an abnormally shaped foundation pit of a subway station using a 2D-FEM model with a focus on deformation behaviors and the effects of stiffness of the retaining structure, the bracing system, soil reinforcement and the soil platform width on the lateral deformation of the retaining structur
