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:

Aiming at the complex finite element method calculation of arch dam static analysis and the shortcomings of low accuracy in solving the dam type optimization problem, a spline semi-analytical method for the static analysis of thin arch dam is proposed based on shell theory and energy principle. It absorbs the general advantages of the spline function method, avoids the cumbersome calculation in the finite element method, and gives calculation examples that meet the accuracy requirements, and compares the results with the finite element method and the arch beam modal method.
