| 摘 要： | 采用电模拟了方法研究了堆石坝的面板和防渗墙产生裂缝时发生的集中渗流，研究结果表明，面权下的基垫层阻断集中渗流，降低坝内浸润线作用显著，实验表明，当防渗墙基础产生裂缝，发生集中渗流时，在坝基设置一定长度的水平防渗板，可以有效地阻隔集中渗流，降低坝内的浸润线。

| Abstract: | The electric analogy method has been used to simulate the converging permeation flow that occurs when crevasses appear in the cover plate and/or the permeation break wall of a rock fill dam. The results show that the filling under the cover plate is important for breaking the converging permeation flow and lowering the soaking level in the dam body. It is suggested that it is necessary to build an additional horizontal plate at the dam base level to block the possible permeation in case the base of the permeation-break wall crevasses cracks. |
