二维平面有限单元法在坝体渗流稳定评价中的应用——以赤泥堆场4^(#)坝北坝段渗流稳定分析评价为例

The application of two-dimensional finite element method to the assessment of the dam seepage stability——basing on the seepage stability assessment of the forth court of aluminum oxide production waste

中铝贵州分公司赤泥堆场4#坝为库中坝,坝为赤泥堆砌而成,其北坝段位于二叠系茅口组、龙潭组交接地段附近,随着该坝的不断加高使用,对该坝北段的渗流稳定进行了分析,其间用到的一些计算方法值得借鉴。

The forth court of aluminum oxide production waste, which belongs to Guizhou branch of China Aluminum Corporation Limited, is the dam in the court. The dam is piled by aluminum oxide production waste; the north part of the dam is located near the junction between the Maokouan Age of permian system and Longtan with a constantly raising use. This study provides an analysis of percolation stability of the north part of dam, some calculation methods are worth using for reference.
