| 摘 要： | 根据重力坝设计规范关于抗滑稳定安全系数和坝踵应力的规定,按断面积最小的要求,考虑上游坝面有折坡、上下游面有水压荷载、坝底扬压力呈折线分布、上游面有泥沙压力等情况,推导出求解重力坝坝前加固断面的参数方程以及最优解的判别式,以便手算进行优化设计。文中给出一个算例,说明如何确定基本断面的参数。

| Abstract: | Based on the design code for dam safety factor against sliding and stress of dam heel,with the requirement of minimum dam surface,considering the folding slope of upstream dam face,water pressure on upstream and downstream,the folding line distribution of uplift pressure and sediment pressure on the upstream dam face,the parameter equation of reinforcement section in front of gravity dam and the discriminant for optimal solution were derived.Further,a case was presented to show the process. |
