摘　　要：渗流数值计算是岩体排水设施和仿真模拟、动态分析、效果评价及预测的有效工具。应用边界元数值方法模拟研究了巷道疏干边坡地下水的动态过程。结果表明 ,岩体的渗透系数张量、可疏干孔隙率对疏干排水效果及其动态过程变化产生显著影响。同时可见边界元数值方法模拟断面尺寸较小的排水设施时 。Seepage flow numeration is an effective tool for simulation,dynamic analysis,effect evaluation and forecast of drainage process in rockmass.The dynamic process of the roadway drainage in the side slope is simulated by using boundary element numerical method.Results show that seepage flow coefficient tensor and drainage porosity of rockmass have an obvious effect on the drainage and the dynamic process,as well as the boundary element numerical method is effective on the drainage simulation of small section in size.
