摘要
针对上海轨道交通7号线工程沿线地质变化幅度大、环境保护要求高、承压水治理复杂等特点,以3个车站基坑的降水为例,提出"按需降水、综合治理"的基坑降水原则。通过三维计算等降水设计预测、优化调整基坑设计施工方案、实时远程监测和动态管理等手段,探索出1条有效治理承压水的途径。
Shanghai rail line 7 project has cha-racteristics of changeable geological condition, strict environment protection and complicated confined water treatment,etc. Taking a case of 3 stations' foundation pits, the author put forward the principle of dewatering according to demands & integral treatment. Through a lot of measures, design forecasting by 3D calculation, optimized adjustment construction plan and remote realtime monitoring, etc., an effective way has been explored in this paper.
