摘　　要：针对佛子岭连拱坝的结构特点 ,用三维薄层单元非线性有限元分析研究了典型坝垛的应力分布及坝顶位移变形规律 ,从而进一步掌握了佛子岭连拱坝的变形性态特性 ,亦解释了该坝 1 993年变形“异常”According to the structural character istics of Fuziling multi arch dam,this paper analyses the stress distribution and deformation regularity of a typical dam section with the nonlinear FEM of three dimensional thin layer elements. The deformation behavior of Fuziling multi arch dam is further understood and the physical genesis of 1993's abnormal deformation of the dam is found out.
