摘　　要：本文提出用“广义文克尔地枯”法计算折线形坝基面重力坝坝基反力及法向正应力，用坝基各段的安全系数的加权平均值作为坝整体安全系数。并介绍了AutoCAD中实现程序可视化运行的方法。具有计算准确、使用方便等优点。This paper proposes to use the 'generalized Winkler foundation' method to compute reactive force and normal stress of a gravity dam foundation with a polygonal dam foundation surface,taking the weighted average value of the safety factors for all the dam foundaion sections as the safety factor of the entire dam. The paper also describes the method of realizing program visualized operation in Auto CAD system.
