摘要
从橡胶坝的薄膜内力和平面问题两个基本假设出发,阐明坝体在不同承载工况下的坝袋拉力理论。并按照坝袋的几何性质导出坝体截面各段曲线方程,拟合出坝体截面的曲面外形,为坝体整体的CAE建模和加载计算分析做好准备工作。
On the basis of two fundamental assumptions： the plane strain and the film internal force, this paper states at first the dams bag pulling force principle of different working circumstance. Then according to the geometrical properties of plastic dams, the curve equations of the cutting face are successively derived out, and the curve shape are also fitted. All the above work is prepared for the CAE modeling and loading calculation and analysis of the dams.
