Field records have demonstrated that the dewatering before soil excavation can induce enclosure wall movement of up to 15Â mm. Typically, this deformation is neglected and cannot be effectively restricted by the traditional support schemes.

Analyses of leakage effect of waterproof curtain during excavation dewatering
, 2020The waterproof curtain that is used to block groundwater, leaks occasionally during deep excavation and can have a harmful impact on the surroundings. This study adopts a three-dimensional (3D) fluid-solid coupled finite element model (FEM) to analyze ...
