摘　　要：经过对水库绕坝渗流分析中常用方法的特点进行分析,认为采用水位上升典型时段库水位与绕坝渗流监测孔内水位变幅比判断绕坝渗流的方法是合适的,通过某工程实测绕坝渗流特性的案例分析,表明该方法可以初步判断绕坝渗流的典型性,在排除降雨影响并结合现场检查情况,才能更准确的评价大坝两岸的防渗性能。The characteristics of common methods in seepage analysis around dam are analyzed, it is considered that it is appropriate to use the variation ratio of reservoir water level to the water level in the hole in a typical period to judge the seepage around the dam. A case study of seepage characteristics around a dam is presented, it shows that this method can preliminarily judge the typicality of seepage around dam, rainfall effect is excluded and combines the condition of on-site inspection, can accurately evaluate the anti-seepage performance of the dam banks.
