| 摘 要： | 张沟水库投入运行以来上游坝面塌陷,下游坝坡蠕变、拉裂、鼓凸明显,右坝肩渗水严重。采用二维有限元软件对坝体进行了渗流分析,结果表明:坝体渗流不稳定,最大坝高断面浸润线较高,有可能发生渗透破坏。采用瑞典法、简化Bishop法、推力传递法、摩根斯顿法计算了各种工况下的坝坡稳定安全系数,比较了各种方法的适用范围。

| Abstract: | Zhanggou homogeneous earth-rockfill dam has the problems of collapsed upstream dam surface,obvious crept,cracked and deformed downstream slope and seepage in right abutment since putting into operation.The dam seepage was analyzed by two-dimensional finite element software.The results show that the dam seepage is unstable;the saturation line in maximum height of section is higher.All these things will cause penetration stability destruction.The slope stability safety factor is calculated by Sweden method,simplified Bishop method,thrust transfer method and Morgenstern method under various conditions.And the scope of application of these methods is compared. |
