摘要
以长沙地铁1号线新建西路车站施工为工程实例,对车站周边情况进行勘测,分析明挖法施工可能产生的风险,如深基坑开挖风险、周边建筑物安全性、施工过程的偏压风险以及周边管线施工风险,并提出对围护结构进行动态监测、注浆加固地层、对承受偏压荷载较大的位置进行重点保护、将管线临时改移、永久改迁、就地保护等解决措施.为类似的明挖法施工工程提供了参考.
Taking the construction of the new west road station of Changsha Metro Line 1 as an example, this paper investigates the surrounding situation of the station, analyzes the possible risks of open excavation construction, such as the risk of deep foundation pit excavation, the safety of surrounding buildings, the risk of bias pressure during construction and the risk of surrounding pipeline construction. It also puts forward some solutions, such as dynamic monitoring of the enclosure structure, grouting reinforcement of strata, key protection of the position with high bias load, temporary relocation of pipeline, permanent relocation and local protection. It has provided a reference for similar open excavation construction works.
