摘要
根据不同的风险源结构类型、风险源与新建地铁车站的位置关系、风险源所处地质特点及施工工法等因素,采用岩土工程专业分析软件PLAXIS8.5,对车站主体基坑开挖引起的地面、建(构)筑物沉降进行模拟分析。对不同的风险源提出了相应的技术措施和控制指标,提出施工中应注意的问题,避免了施工时的盲目性,从而确保了施工安全。
Settlement of ground and buildings caused by the foundation pit excavation during construction of the principal part of the golden avenue station（in Changsha Metro Line #6）is simulated and analyzed,using the geotechnical engineering analysis software PLAXIS8.5 and considering the structural type and protection level of risk source,the location of risk source relative to new rail transit,geological characteristics of the affected area,and construction methods. Corresponding technical measures and control index are proposed for different risk sources. The problems that need to be noted during construction are put forward to ensure the construction safety.
