| 摘 要： | 采用三维静力有限元法,基于邓肯-张非线性弹性模型,模拟了双江口高心墙堆石坝在竣工期、蓄水期的应力与变位.研究了应力分布和极值应力的量值、区位.计算结果最大沉降变位为2.907m,约占坝高0.93%,与类似工程相比沉降占坝高百分比较小.对上游堆石应力水平较高区域给出了工程建议.

| Abstract: | Stress and displacement of the high core rock-fill dam of Shuangjiangkou HPP,in the process of dam construction and impounding,is simulated by 3-dimensional static finite element method and based on Duncan-Chang nonlinear elastic model,with stress distribution and high stress field of dam obtained.The results of calculation demonstrate that the maximum settlement is 2.907m,or 0.93% of the dam height,a small percentage compared with similar projects.Engineering suggestions are presented for the high stress zone on the upstream surface of the dam. |
