摘要
借助于弹性力学平面问题的基本理论可以得到混凝土重力坝较为精确的应力分布。具体求解时可以先通过静力等效简化分解力学模型,然后利用平面问题的基本方程和边界条件分别求出不同情况的应力解,最后将这些应力解对应叠加,得到原始模型的应力解。
More exact stress distribution for different positions in the body of concrete gravity dam can be given by means of basic theory of Elastic Mechanics on the two-dimensional problem. It may be decomposed into three steps for the specific solution processes. Firstly, simplify and decom- pose the mechanical model according to the theory of static equivalent. Then, calculate the stress distribution for different situations using the basic equations and boundary conditions of theory for two-dimensional problem. Finally, adding the corresponding stress together to get the results for the original model.
