摘要
为将运营地铁上盖项目基坑施工过程中对地铁设施的影响降至最小,结合上海某项目基坑施工实际,对地铁上盖项目基坑施工过程中的风险应对措施进行了研究。从建设阶段风险要点分析、建设安全筹划、地铁隧道区间纠偏、围护体系缺陷事先处理等几方面,对基坑的施工安全风险防控做了详细介绍,以期为类似工程提供经验借鉴。
To minimize the impact on the subway facilities during the construction of the foundation pit of the subway upper cover project,this paper studies the risk response measures during the construction of the foundation pit of the subway upper cover project in combi nation with the actual constructio n of the foun dation pit of a project in Shanghai.The construction safety risk prevention and control of the foundation pit are introduced in detail from the aspects of the analysis of risk points in the construction stage,the construction safety planning,the deviation rectification of subway tunnel interval,and the treatment of the defect of support system in advance,so as to provide experience for similar projects.
