| 摘 要： | 基础变形模量对坝体的安全运行和受力有着十分重要的意义，特别是高拱坝，需要良好的基础变形模量，但是在一定的荷载运行工况下，并不是意味着基础变形模量越高坝体应力、稳定、变形状况就越好。基于上述观点，利用多目标非线性规划方法对锦屏拱坝最优基础变形模量进行了研究，给出了拱坝在最优基础变形模量条件下坝体应力、稳定、变形及基础处理费用等特征值。研究表明：经过基础变形模量的优化，能有效改善坝体应力、位移、稳定等多项指标。

| Abstract: | Foundation deformation modulus has vital importance for the safe operation and external loads bearing of dams,especially for high arch dams which need good geological condition and foundation modulus.However,under condition of a certain loads and initial foundation deformation modulus it doesn't mean that the higher the foundation deformation modulus the better situations of stresses,stability,displacement and the cheaper the foundation treatment fee will be.Based on this viewpoint,a multi-objective non-linear programming method is applied to study the optimal foundation deformation modulus of Jinping arch dam in this paper.After the optimization study,the eigenvalues of stresses,stability,deformation,and foundation treatment fee have been calculated as well.It is proven that through optimizing the foundation deformation modulus of arch dam the situation of stresses,displacement and stability of the dam can be ameliorated. |
