邻近地铁基坑围护结构的设计及变形控制措施

Design and deformation control measures for enclosure structure of foundation pit adjacent to subway

本文介绍了某邻近在建地铁设施的基坑工程围护结构的设计及相关变形控制措施,内容主要包括工程概况与环境条件、工程地质条件、围护方案选择、围护体系具体做法、针对重点部位的技术措施、围护结构计算分析、应急措施及过程监测等,可供类似条件下的基坑工程借鉴参考。

This paper introduces the design of the enclosure structure of a foundation pit adjacent to subway and related deformation control measures.The contents mainly include the engineering overview and environmental conditions,engineering geological conditions,selection of enclosure structure schemes,specific practices of the enclosure system,the technical measures of the key parts,the calculation and analysis of the envelope structure,the emergency measures and the process monitoring,etc.This paper can be used for reference to the foundation pit engineering under similar conditions.
