Research on small-scale pit is carried out using VE principle in this article.

This paper ustilizes seepage rationale to large-scale foundation pit apportion and calculation,systematical design,and sets up well point dewatering seepage curvilinear equation in order to better estimate watermark,reasonably arranges well point,and scientifically corroborate plan of.

The key of super-large foundation pit engineering in soft soil is to control the deformation, the deformation control is mainly related with the selection of supporting and bracing system and construction method, which involved many factors.

Subsoil engineering properties and reinforcement of large-scale pit filled in Cangzhou;
