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。
The change law of phreatic line under different working conditions is obtained by the numerical simulation for ash fields seepage flow.
通过对渗流作用下贮灰库的数值模拟计算,得出了各种工况下贮灰库浸润线的变化规律。
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;
To ensure the heightening engineering of tailing dam to successfully carry through, siphonic drainage system was adopted to lower the phreatic line in the dam.
