摘要
降雨是影响排土场安全的重要因素。以某高台阶铁矿排土场为例,根据饱和—非饱和的渗流规律,利用有限元方法,对非降雨和降雨条件下的排土场进行稳定渗流和瞬态渗流分析研究,结果显示降雨对该排土场渗流场分布影响较大,为该排土场的安全治理与工程设计提供重要依据。同时可以为类似排土场安全分析提供参考。
Rainfall is an important factor for the safety of waste dump. A waste dump with high bench is taken as an example. According to the saturated-unsaturated seepage theory, the stable seepage and transient seepage of the waste dump in the condition of rainfall and non-rainfall are analyzed with the finite element method. The result shows that the rainfall makes significant influence on the safety of waste dump. It provides an important basis for the security governance and engineering design, which can be a reference for the safety analysis of similar waste dumps.
