摘要
坝体加宽后,原有中部溢流挡墙不能满足要求。运用三维有限元数值方法计算分析坝体加宽后改进的溢流挡墙的应力变形。结果表明,坝体拓宽后各种方案溢流挡墙均可以安全运行;通车方向对溢流挡墙有影响,但影响不大;上下游水位越低,溢流挡墙安全性越差。
After the dam is widened, the original central overflow retaining wall cannot meet the requirements. The stress and deformation of the new design is studied with the 3D-finite element method. The calculation results show that the overflow retaining wall can be operated safely; the direction of the vehicle driving has little effect on the overflow retaining wall; the lower water level is lower and the safety of overflow retaining wall is worse.
