摘　　要：作为土石坝的重要挡水结构,混凝土面板属于薄体结构,受力非常复杂。为节省工程投资,大坝面板大多设计为素混凝土结构,面板在面临极端外界条件下易产生不规则开裂。诱导缝的设置可以在不影响面板连续浇筑的前提下控制裂缝的产生及发展,从而保障土石坝面板的安全运行。本文结合某水库实际情况,采用ANSYS三维有限元软件对土石坝面板进行三维仿真分析,得出面板结构在不同工况下应力的一般分布规律,为土石坝面板诱导缝设计提供技术支撑。As an important retaining structure of earth-rock dam,concrete panel belongs to thin body structure and its force is very complicated.In order to save project investment,most of the dam panels are designed as plain concrete structures,which are prone to irregular cracking under extreme external conditions.The installation of the induced joint can control the generation and development of cracks without affecting the continuous pouring of the face panel,so as to ensure the safe operation of the face panel of earth-rock dam.In this paper,based on the actual situation of a reservoir,the three-dimensional simulation analysis of earth-rock dam panel is carried out by using ANSYS three-dimensional finite element software,and the general stress distribution of the panel structure under different working conditions is obtained,which provides technical support for the design of the induced joint of the earth-rock dam panel.
