摘　　要：基于积函数极值法，确定了刚度分布未知的挡水坝的地震剪力和地震弯矩上限。计算表明，本文的理论解与文献［１］，［２］的数值计算结果是一致的。In this paper, based on the method of extremum of product function, theoretical so- lutions in closed form for the upper bound seismic shearing forces and bending moments of retaining dam are derived. Examples show that the calculation results from threoretical solu- tions are identical with those from numerical methods in References[l] and [2].
