摘要
鉴于定值计算方法(纯拱法、拱梁法)的机械性和有限元法的复杂性,依据力学原理,利用积分手段,提出了抛物线拱坝水平拱圈荷载传递的简化连续分析方法,总结出了抛物线拱坝水平拱圈支承力衰减的基本规律,为拱坝的优化合理设计提供了一个更为有效的理论依据。
Because the True Arch Method and the Arch-Beam Method were mechanical, and the Finite Element Method was complicated, a simplification continuous analytical method of load transmission on horizontal arch of the parabola arch dam has been put forward according to the principle of mechanics and the integral calculus. The basic regularity of horizontal arch supporting force attenuation of the parabola arch dam has been discovered, which provides an effective basis for optimization design of arch dam in theory.
