Study On The Design Parameter And Application Effect Of In-depth Agitation Pile Anti-seepage Wall

At present, there are many different anti-seepage measurements used in water conservancy project at home and abroad. Some anti-seepage measurements need large investment, large work and have great difficulties and then they are rarely used. Some anti-seepage measurements have the advantages of high implementation speed, small investment and excellent anti-seepage effects, while there is little practical experience and real cases for them. Then they are also seldom used in the real project. Currently, in Shandong Province the technology application of in-depth agitation pile anti-seepage wall is in the latter situation.In-depth agitation pile is a way to strengthen soft land originally. And it is mainly used to improve the carrying power of the base and decrease the sinking amount. It is used in many different fields since its implementation is convenient, economical, reasonable, as well as without pollution. Now, the in-depth agitation pile is also used commonly in water conservancy project. The mainly form is to form agitation pile anti-seepage wall to decrease the transfusion of water on land and below the land and limit confusion and hill sinking. There are some successful cases on this aspect while the theory research is rare and the usage of the designed target hasn't form a systematical theory system.This paper connects the base anti-seepage in the project case of Weihe Zuoshan Rubber Dam. It also give a general analysis of the application fields, theory of the anti-seepage and application conditions through the analysis of geographic resources and confusion stable calculation based on the detailed research on the domestic and foreign dam base anti-seepage schemes. During this process, different assessment indications are adopted to give the analysis confirmation for the structure forming of in-depth agitation pile anti-seepage wall and the date of cements involving ratio.This paper is to offer a real example for the promotion and application of in-depth agitation pile anti-seepage technology.
