| 摘 要： | 采用边界元法研究无限深透水地基上土石坝铺盖长度对坝基渗流的影响。土石坝坝基渗流量随铺盖的延长逐渐减小，并呈抛物线形分布；当铺盖长度达到一定值时，水力坡降稳定且渗流量的变化也不明显。由此，提出了建在无限深透水地基上的土石坝水平铺盖长度与坝前水头的关系。

| Abstract: | This paper introduces the boundary element method to study the affect of the blanket length for earth-rock dam on the infinite deep pervious foundation on the seepage of dam foundation. The seepage discharge of the foundation of earth-rock dam decreases gradually and is in a parabola form as the blanket extends. If the blanket length reaches certain value, its hydraulic gradient is steady and the variety of seepage discharge also not obvious. This paper puts forward the relation of water head and blanket length of earth-rock dam on the infimte deep pervious foundation. |
