某净化站边坡水池渗漏影响评估及处置建议

Leakage Impact Assessment and Proposed Disposal of Some Decontamination Pool Slope

某边坡位于黄河北岸的虎头嘴北侧,其坡顶设置了2个直径100 m的净化池。为了保障边坡稳定及净化池安全工作,必须对净化池的渗漏影响进行评估。根据边坡工程地质条件,对净化池的渗漏影响进行了模拟分析。结果表明:边坡下部存在的砂卵石层对净化池渗漏后的水起到很好的疏导作用,使净化池的渗漏影响控制在一个较小的范围之内。建议在边坡设计中应根据渗漏影响范围对边坡稳定性进行校核。

The study slope is located at the north side of the Hutouzui of the north bank of the Yellow River, two pools with 100 meters diameter was set on the top of the slope. In order to protect the slope and the purification pools, we must evaluate the effect of leakage of the pools. Simulation analysis was carried out based on engineering geological conditions of the slope to evaluate the effect of the leakage of the purification tank. The results of the analysis shows that the existence of the sand and gravel layer in the slope plays a role of filtrating the water flow from the purification tank leakage so that the effect of leakage of purification tank may be controlled to a smaller area. Slope stability should be checked in slope design according to the area of leakage effect.
