Abstract: Zishancun Dam is a homogeneous earth dam.It has been operating in severe seepage because of poor foundation and dam body construction for a long time. The saturation line decreased 0.6~3.0m by means of using well and ditch diverting, improving drainage system downstream, so that the perils has been eliminated. It proved that well and ditch diverting is an effective treatment measures. It has characters of simple technology,easy construction and small cost. It effectively decreased saturation line of dam body, corrected seepage flow direction and improved the safety factor against sliding of dam slope downstream.?

摘要： 梓山村水库大坝为均质土坝，由于基础及坝体施工不良等方面的原因，长期以来，存在较为严重的渗漏，时刻危及大坝的安全。通过采用导渗井、沟，完善下游排水设施处理后,坝体浸润线降低了0.6～3.0m，安全隐患得以消除。实践证明，井沟导渗是一种技术简单,施工容易,投资较少,能有效降低坝体浸润线,改变渗流出口方向,提高下游坝坡抗滑稳定安全系数的土坝渗漏治理方法。
