| 摘 要： | 在有限元计算大坝的渗流场和应力场的基础上,对大坝渗流场的分布规律及其对坝坡稳定性的影响进行了详细分析,弄清楚了大坝产生异常渗流的原因,揭示了大坝内部异常渗流和开裂的关系。研究结果为大坝的除险加固设计提供了理论依据,也可为今后土坝的设计施工起到指导作用。

| Abstract: | On the basis of calculating the seepage field and stress field of the dam with FEM, the seepage field distribution law and its influence on the stability of dam are analyzed in detail. The reasons for abnormal seepage in the dam are revealed and the relationship between abnormal seepage and cracking is finally released. The results offer a theoretical basis for the reinforcement of dams and give a guidance for the design and construction of earth dams in the future. |
