摘要
采用Oden等提出的非局部摩擦模型代替经典的库仑摩擦模型对重力坝坝基面的摩擦力进行分析,推导出了重力坝坝基面摩擦力的积分形式,并通过用Maple语言进行编程计算,求得其数值解.将所得的解与库仑摩擦模型下的解进行比较可知,这个结果是合理有效的,这将对实际工程中的重力坝的抗滑稳定分析和坝基面的应力分析有一定的参考价值.
In this paper, the nonlocal friction law proposed by Oden et al is applied by analyzing the friction of the gravity dam along interface between dam and foundation , the equation of the integral form is obtained and solved by programming with Maple language, and its number solution is given. Compared with the solution to the local friction law, the results are effective.
