摘要
对石灰岩地区大坝基础的１０个钻孔进行天然和人工两种流场同位素示踪测量，测定出地下水流速矢在切平面和垂直面上的分布，根据水平和垂向流速的大小和方向绘制出大坝的渗漏点和渗漏路径。依据测量结果，大坝首次灌浆处理获得成功，水库的渗漏水量比灌浆前减少６０％。
The leakage of a reservoir located in Karst region was studied using isotopic tracing techniques.Ten drilling wells were scattered around the dam area and the distribution of velocity vector of ground water in tangent and vertical planes were determined under natural and artificial flow field.The leakage points and paths were drawn up based on the amount and direction of the horizontal and vertical veloicty.The first treatment of cement grouting followed the determined results met with success by a 60% reduction of reservoir leakage.
