Simulation and Analysis of the Failure for the Water Stop Curtain of Building Pit in Round Gravel Level

The failure of the water stop curtain is a hot engineering problem which is usually seen in deep building pit constriction. In this paper, the SEEP/W module in Geo-Studio is adopted to simulate and analyze the failure of the water stop curtain and the geological condition in a certain project. The curtain defect existed in the round gravel level and its effect on the filtration is also studied. Finally, the strategies for controlling the quality of the water stop curtain are summarized.
