摘　　要：为新疆无限深透水地基土石坝寻求理论上较精确的渗流计算方法,采用直接边界元法,提出了对于修建在无限深透水地基上具有水平铺盖防渗体的土石坝渗流计算模型。通过对新疆多浪水库库区第四系全新冲洪积物覆盖层的渗流计算,对比计算和实测渗流自由面,验证了模型的可行性,可供设计人员参考。Many earth - rock dams in Xinjiang Uygur Autonomous Region of China are built on infinite deep pervious founda- tion. For infinite deep pervious foundation, there is no accurate method for seepage calculation in theory till now. We use direct boundary element methol to establish a seepage calculation model for earth - rock dam with horizontal impervious blanket system built on infinite pervious foundation, Then the feasibility is verified by comparison with the free seepage surface.
