摘　　要：从橡胶坝的薄膜内力和平面问题2个基本假设出发,阐明坝体在不同的承载工况下的坝袋拉力理论。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了准备工作。On the basis of two fundamental assumptions-the plane strain and the membrane stresses, this paper firstly describes the dam-bag tension theory at different working conditions. The curve equations of different sections are successively derived according to the geometrical properties of plastic dams, and the shape of the dam are generated. All the above work is prepared for the dam CAE modeling and loading calculations.

关 键 词：坝袋拉力 曲线方程 建模 加载
