摘　　要：大花水拦河大坝为河床拱坝＋左岸重力坝的组合坝型，拱坝最大坝高134．50m，重力坝最大坝高73m。拦河大坝稳定分析包含碾压混凝土拱坝和左岸重力坝，本文主要介绍大花水拦河大坝稳定分析在不同设计阶段中的分析情况。The abutment stability against sliding in the design of arch dam is vitally important. The rational stable sliding pattern and accurate load calculation can obtain the reliable safety factor of stability against sliding and ensure the safe operation of arch dam, and at the same time, too conservative will result in a waste of investment. In the calculation of stability against sliding, some noticeable questions of sliding pattern choose, slide block boundary condition determination, main load calculation and calculation result analysis are introduced based on the practice of some projects.
