| 摘 要： | 本文通过三维有限元对比分析,随着闸门启闭方式改变、闸墩上部加固改造后闸墩的各部位最大拉、压应力值及应力分布均相比加固前有较大变化,尤其是在牛腿、闸墩新老混凝土及液压杆支绞座处等应力明显集中、增大,计算结果可为溢流坝段的安全运行提供技术支撑.

| Abstract: | Through 3D finite element comparative analysis, this paper finds out that after reinforcement and changing the way of opening and closing, the largest tensile and compressive stress and the stress distribution in the pier changes a lot. Especially in the bracket, new and old concrete and the ground base of hydraulic lever, the stress concentrates and increases obviously. The calculation results can provide technical support for safe operation of the overflow dam. |
