| 摘 要： | 对吴岭水库大坝出现异常散浸及发生局部滑坡的坝段进行有限元渗流计算及坝坡抗滑稳定计算,分析了坝段存在的强风化砂岩与残坡积土的强透水层对大坝渗流及稳定的影响.计算结果表明,由于坝段存在的强风化砂岩与残坡积土强透水层,使得坝体内部浸润线抬高,大坝下游坝坡在比较高的位置出现大面积异常严重的散浸,并导致坝坡抗滑稳定性能大大降低,因而使得坝坡产生局部失稳现象,所计算出的散浸区域及存在滑坡危险区域与实际一致.

| Abstract: | The seepage FEM calculations and the dam slope stability analyses are conducted for Wuling hydraulic project. The influence of the strong perviousness of the alluvium and seriously weathered sandstone in foundation on the seepage field and the dam slope stability are analyzed. The calculation results are agreed well with the project shows. It is concluded that the abnormal seepage problem and the unstableness on the downstream dam slope are caused by the strong perviousness of the alluvium and seriously weathered sandstone in foundation. |
