    • Abstract
  • Based on the deep excavation project of Shanghai Qiantan Block 33-01, the choice and analytic thoughts of deep excavation support systems are put forward for the hydrogeological conditions of deep confined aquifer in soft soil areas. The technical countermeasures corresponding to the control of confined groundwater of the deep excavation are introduced. In order to reduce the the adverse effects of pit construction on the surrounding environment, the confined water layer is blocked by the CSM method constant-thickness cement-soil wall. The monitoring data indicate that the surrounding environment is effectively protected by the proposed support design and implementation. Furthermore, these solutions may provide valuable reference for other similar projects in soft soils.
