Combined with a project,it analyses its layer distribution and soil property,puts forward detailed dewatering plan and detailedly introduces the concrete construction situation and the measures in the construction,the influence of dewatering in clay area to the architecture in its neighborhood was discussed,to accumulate the experience of the dewatering construction.

In conjunction with project practice,the article is focusing on design and study of the well point dewatering plan of deep and light-sized wells in combination,including calculation of surge amount,parameter study on determination of number of dewatering well,and well spacing set-out.

On the selection of implementation of foundation pit dewatering scheme

Combined with practical work and based upon analysis of geological conditions the dewatering scheme is selected,at the same time corresponding measures are proposed for dewatering treatment of elevator shaft.

This paper introduces the construction situation of a certain subway station adopting open-cut construction and selecting drilled piles as fencing structure,analyzes the types and buried depth of groundwater,calculates the construction dewatering,and determines the dewatering scheme.

The example analysis and comparison of the well-point method precipitation program;

With the precipitation simulation of summer in China, the cloud-precipitation schemes of model are examined.

By the analysis for the orthogonal experiments,the optimum scheme of bolt parameters is conformed.

The requests to heat insulation and gastightness of warehouse for low temperature grain storage and an optimum scheme of low temperature grain storage for three ecological areas were provided respectively.

Through analyzing the ecological characteristics in Meng-Xin area, the optimum scheme for grain safe storage of this area was put forward.
