软土地区地铁永久性结构变形影响因素的研究

Studies on Influencing Factors of Metro's Permanent Structure Deformation in Soft Soil Areas

基于软土地区长期监测的地铁永久性结构的变形数据,对累积沉降量、差异沉降量、沉降发展趋势及沉降因素等进行研究,根据沉降现状与规律关联性,综合工程地质条件等变形影响因素,初步分析软土地区地铁永久性结构变形的主要原因,为地铁规划建设和运营管理提供参考依据。

Based on data of deformation of metro ＇s permanent structure on long-term monitoring in soft soil areas , this article studies accumulated settlement ,differential settlement ,settlement ＇s developing tendency and factors .Accord-ing to settlement situation and inner connections , combining deformation ＇s influencing factors of engineering geological condition,preliminary analysis has been made on the main causes of deformation of metro＇s permanent structure in soft soil areas ,thus providing references for metro＇s planning ,construction ,operation and management .
