摘要
应用有限元分析某尾矿坝的浸润线,认为(1)尾矿坝浸润线与放矿滩长有关系,随着放矿滩长加大,浸润线远离砂砾石坝体.从有限元模拟情况可知放矿滩长大于70 m时各工况下浸润线不在坝趾出露,这时坝体是稳定的.(2)对于建在透水性强的坝址上的尾矿坝,坝体的填筑高度对浸润线在坝趾出露影响不明显.
Saturation line is the lifeline of tailing dam. This article analyzes one tailing dam saturation line by finite element method, the conclusions are. （1）The tailing dam saturation line is related with the drawing beach length, with the beach length increasing, the saturation line become far from the grit dam body. When beach-length is more than 70 meters the saturation line away from the dam＇s foot according to the conclusion of finite element simulation, the dam is stable. （2） The tailing dam is built on the strong water penetration site, the dam＇s height influences saturation line isn＇t distinct in the dam＇s foot.
