摘　　要：本文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 ,推导出求解重力坝基本断面参数的二次方程以及最优解的判别式 ,以便人工手算进行优化设计 .This paper presents a quadratic equation and some formulas for manually calculating the parameters of primary section of gravity dam according to the design criteria and the principle of minimum section area. The configuration of the dam section may be a vertical or/and an inclined faces under dead weight, with water pressure acting on upstream and downstream faces, silt pressure, uplift pressure distributed in the shape of a broken line. Two examples are given for demonstration.
