水位变化与降雨耦合条件下四川某渣场边坡稳定性研究

Study on the slope stability of slag landfill slope under the coupling effect of water level change and rainfall

基于有限元软件Geostudio,分析了四川某渣场堆填体边坡在不同工况下的渗流场和稳定性。结果表明:江水位的升降主要影响堆填体边坡前缘地下水位,降雨对其地下水位的影响不明显;堆填体边坡在高水位时的稳定性低于低水位的稳定性,降雨对堆填体稳定性的影响作用不明显,堆填体边坡在江水位变化和降雨联合作用下处于基本稳定状态。

Based on the finite element software Geostudio,the seepage field and stability of a slag were analyzed.The results have shown that the fluctuation of river water level mainly affects the groundwater level at the front edge of the landfill slope,and the effect of rainfall on the underground water level is not obvious.The stability of the landfill slope at high water level is lower than that at low water level.The effect of rainfall on the stability of accumulation body is not obvious,and the landfill slope is basically stable under the combined action of river water level change and rainfall.
