结合对某矿黄土基底排土场的工程实践与试验研究，对演化弱层的流动变形特性做了进一步的探讨。

Combined with engineering practice and test study of loess basement dumping site in a coal mine. More probe to flow deformation feature for evolution soft layer is given here.

但在设计时必须考虑在排土增至一定高度后，弱层的形成对排土场稳定性的影响，否则必将会存在重大滑坡隐患。

But their influence on the stability of the discharge field slope must be considered in order to avoid the danger of landslides.
