1·The phreatic line is increased enormously and dam stability is threatened in flood.
在洪水运行工况下，浸润线大幅度升高，对贮灰库的稳定极为不利；
2·The paper deals with the law of ground water movement in the slope and analyzes the effect of high phreatic line in the bulk on the slope stability.
本文从研究边坡中地下水运动规律入手，分析坡体中的浸润线位置过高对边坡稳定的影响。
3·The tailings dam in the Third Baiyin Smeltery is a damaged dam. To secure the dam, radial collector well is applied to cause a drawdown of The phreatic line.
白银公司三冶炼厂尾矿坝是一座险病坝，利用辐射井排水降低坝体浸润线的措施，保证了坝体的安全。
4·The phreatic line is higher at upstream-type tailings dam and most of dams are in saturated state, thus easily leading to flow slide destruction under earthquake.
上游法尾矿坝浸润线较高，大部分坝体处于饱和状态，地震作用下易发生液化流滑破坏。
