摘要
在地铁车站的施工过程中,常发生施工顺序及进度的变更,必须通过优化结构设计或者调整施工部署解决上述冲突。文章以某地铁车站建设项目为案例,采用理正单元计算,与Midas整体计算对比了提前插入主体结构施工对基坑的安全性的影响,并针对所采用的盖挖逆作法进行调整,对其安全施工提出了建议。
In the process of subway station construction,the construction sequence and schedule are often changed,and the above conflicts must be solved by optimizing the structural design or adjusting the construction deployment.This paper presents a case study of a subway station construction project,comparing the impact of early insertion of main structural construction on the safety of excavation using Lizheng unit calculations and Midas comprehensive calculations.Adjustments are proposed for the adopted top-down excavation method to ensure safe construction.
