摘　　要：本文采用Lagrange方法给出了具有倾斜承压面的刚性坝地震时所承受的动水压力。计算结果表明:对于垂直坝,本文结果精确符合Westergaard的结果;对于不同倾角的斜坝,本文结果较好地符合Zangrf和Haefeli的实验结果,本方法还适用于计算计及自由面波动影响的非线性动水压力,This paper gives the evaluation of the dydrodynamic pressure on a dam with an inclined upstream face due to the agitated water by the horizontal earthquake force using the Lagrangian approach. Results obtained in this paper agree very closely with that of the results by Westergaard for damswith vertical upstream faces and agree fairly good with the experimental results by Zangar and Haefeli, The method in this paper may be extend to determine the nonlinear dydrodynamic pressure on dams by the agitated water taking consideration of the influence of the free surface wave of the water.
