软土地区基坑围护设计与监测成果对比研究

A comparative study on retaining design and measurement result of excavation in soft soil area

针对软土地区的地质特点,结合拟建基坑实际情况,确定了安全、可靠的围护设计方案,在基坑施工过程中,通过基坑监测掌握围护结构变形情况,确保基坑始终处于安全可控的范围内,并结合实际案例对基坑围护设计及监测进行分析,其结果可为上海同类型基坑围护设计与施工提供参考。

Against the geological characteristics of soft soil, combining with the actual situation of proposed excavation, identify a safe and relia-ble retaining design. In the construction process of the excavation, through the measurement to grasp the deformation of the retaining structure, to ensure that the excavation is always in a safe and controllable range. This paper analysis the retaining design and measurement of the excavation by practical case, the results can provide reference for the retaining design and construction of the same type of excavation in Shanghai.
