利用抽水试验测定防渗墙渗透系数

Penetration coefficient determination using pumping experiment of anti-seepage wall

目前对防渗墙整体渗透系数的检测,工程极少采用。颍上县孟洼排涝站,利用抽水试验测定了防渗墙整体的渗透系数,避免了以点代面的弊端。

The current measurement to examine the whole permeating coefficient of the seepage wall is little used in the project. In Mengwa drainage of stagnant water station which is located in Yingshang county, the whole permeating coefficient of the seepage wall is examined by pumping experiment. The conclusion not only avoids the generation of the point defects, but also reduces the cost of testing.
