摘要
降雨入渗不仅会导致边坡孔隙水压力的增加和基质吸力的降低,还会引起地下水位上升及岩土体抗剪强度的减弱,从而对边坡稳定性产生不利影响,针对此,文中以海外米拉多铜矿南排土场边坡工程为研究对象,通过FISH语言编程将多个功能模块嵌入FLAC3D,成功实现了FLAC3D中饱和渗流分析到饱和-非饱和渗流分析的转换,并将该方法有效应用于南排土场的计算模型中,进一步探讨了降雨强度及持时对渗流场、位移场及稳定性的影响,有利于完善边坡稳定性分析的理论体系。
During rainfall infiltration,increased pore water pressure,reduced matric suction,rising groundwater levels,and weakened shear strength can all adversely affect slope stability.This study focuses on the south waste dump slope at the Mirador copper mine.By embedding multiple modules into FLAC3D using FISH scripting,we achieved a transition from saturated to unsaturated seepage analysis,applying it effectively to the project model.The impacts of rainfall intensity and duration on seepage,displacement,and stability were analyzed,providing theoretical and practical support for similar projects.
