| 摘 要： | 在对大河水电站面板堆石坝施工期洪水作用下坝体与坝基渗流场进行有限元模拟的基础上,根据极限平衡理论并考虑了堆石体材料的非线性强度参数对渡汛时坝坡的稳定性进行了研究.计算结果表明,该坝剖面在施工渡汛期,渗流稳定及上下游坝坡稳定能满足规范要求,汛期安全性有保障,为设计方案研究提供了重要参考. |

| Abstract: | Based on numerical simulation of the seepage field of the temporary dam body of DaHe CFRD using FEM(Finite Element Method) under action of river flood during construction period,the stability of the dam slope is studied with limit equilibrium theory considering rock's nonlinear shear strength.The results indicate that the stability of dam slopes could meet the requirements of the standards;and it is safe during the flood period so as to offer important reference to engineering design. |
| Keywords: | concrete faced rockfill dam slope stability flood control during construction period finite elements seepage field |
