| 摘 要： | 针对拱坝静力分析的有限元法计算复杂，且存在解决坝型选优问题时精度不高等缺点，以壳体理论和能量原理为基础，提出了薄拱坝静力分析的样条半解析法．它吸收了样条函数方法的一般优点，避免了有限元方法中计算繁琐的不足，且能满足精度要求．给出了计算实例，并与有限元法和拱梁模态法的结果进行了对比．

| Abstract: | Based on the theory of shells and variational principle,with the spline finite element method,a semi analytical method which is used to analyse thin arch dams is presented in this paper.It overcomes the shortcomings of finite element method with heavy computational work and expensive cost of solution.Compared with the finite element method and other numerical methods,this method proves to be adequately accurate and highly effective. |
