摘要
以深圳市某深基坑工程为例,考虑到基坑开挖对地铁结构安全可能产生的不利影响,设计了两种控制变形较好的支护方式,通过数值模拟不同支护方式下基坑开挖的动态全过程,对其进行了评价并对基坑支护方案选择和施工措施提出建议,结合监测资料与数值分析结果进行比较,结果表明,数值分析与实际监测吻合较好。
Considering some deep foundation excavation project in Shenzhen adjacent to Shenzhen Metro Line 2, two different types of supporting systems were accordingly designed and the corresponding construction processes were simulated considering the potential adverse influence on metro structures. In this way, the appropriate supporting type was chosen as the supporting system and some suggestions were proposed for the actual construction control according to the analytical results and comparison. It has been shown that actual deflection curves from collected monitoring data have the trend similar to the predicted results.
