摘　　要：针对存在水平强透水层的均质岸坡在库水位等速下降条件下计算浸润线问题,通过室内物理模拟试验研究了均质岸坡存在水平强透水层时库水位等速下降对岸坡土体内浸润线的影响,对比了模拟试验与理论计算获得的浸润线结果,并基于试验结果的拟合提出了存在水平强透水层的均质岸坡在库水位等速下降条件下计算浸润线的简化方法。Aiming at the problem of calculation the bank slope phreatic line, the influence of the reservoir level uniform lowering on the phreatic line of the homogeneous bank soil slope with a horizontal high pervious blanket is studied by the indoor physical simulation test. The simulation test result of phreatic line is compared with that of the theoretical computation method. Based on the test result, a simplified method to calculate the phreatic line under the conditions of reservoir level uniform lowering is proposed.
