Pit Dewatering for Double-layer FoundationShao Li-ju a n, Bi L in g, Cao Ren-ciAbstract ] Compared with ordinary foundation structure, double-layer foundation is more prone to deformation and damage due
to infiltration. Therefore, the drainage and dewatering treatment o f the foundation must be done well in the design and construction o f the
double-layer foundation. A brief analysis of the structural characteristics o f double-layer foundation is made using investigation method,
experiment method, literature method,etc” and then how to design double-layer foundation drainage decompression and foundation pit
dewatering is explored, which hopes to provide some theoretical reference for related practical work.[Keywords ] double-layer foundation ; drainage decompression ; dewatering design= ? ? ? j )? ? ? ? ` H ? ? ? ? q ? ` ? )X
