摘要
基于地铁车站紧急联络通道下穿建筑物开挖过程中极易引发的较大变形问题,对下穿过程隧道沉箱基础变形和加固措施进行总结分析,采用有限元分析软件对下穿过程进行数值模拟,根据现场监控量测数据结果分析效果。结果表明:由于上部沉箱的棚架作用,开挖过程中初期支护主要承受初期支护及沉箱间覆土的厚度及较小部分沉箱下传的作用力,研究结果可为类似项目施工提供借鉴。
Based on the large deformation problem easily caused by the excavation of the underpass building of the emergency communication channel of the subway station, the deformation and reinforcement measures of the tunnel and caisson foundation during the underpass process were summarized and analyzed. The finite element analysis software was used to conduct numerical simulation of the underpass process, and the effect was analyzed according to the results of the on-site monitoring and measurement data. The results show that, due to the scaffolding effect of the upper caisson, the initial support mainly bears the thickness of the initial support and the covering soil between caissons,as well as the downward force of a small part of caissons. The research results can provide reference for similar projects.
