摘要
建立开裂约束下拱坝体形优化设计模型,在5种工况下采用改进的复合形法对拱坝体形进行常规优化设计,然后采用三维非线性有限单元法,研究不同工矿下拱坝的开裂位置和深度,以探讨拱坝开裂对其他工矿下坝体应力状态的影响.实例计算得出了比较合理的拱坝优化体形.
A numerical model is developed for shape optimum design of arch dams under restriction on cracking, and it is applied to general shape optimum design of a double-curvature arch dam under 5 working conditions by use of the improved complex method. Three-dimensional nonlinear finite element method is adopted to study the location and depth of cracks in the arch dam under different working conditions as well as their influences on the stress state of the dam body under other working conditions. A reasonable shape of the arch dam is finally obtained.
