基坑工程截水帷幕的设计分析

Design of Groundwater Cut-off Curtain in Deep Excavations

截水帷幕的设计是基坑支护设计的重要内容,针对基坑工程中截水帷幕的类型,分析了不同截水帷幕的主要设计参数、常见问题及应对措施,对基坑工程止水帷幕的设计和施工具有一定的指导意义。

The groundwater cut-off curtain is one of the important aspects in the design of deep excavation supporting system. This paper introduces the type of cut-off curtains that applied in the deep excavation engineering; these types including cement mixed soil columns, jet grouts, and pressure grout formed curtains. The major design parameters as well as the commonly encountered problems and their solutions in each type of the curtain are also introduced.
