Application of Thin Layer Elemet in Finite Element Method of Analysis for Xiluodu Arch Dam

AbstrcatIn the Xiluodu Arch Dam aralysis,thin layer element were used for the dam body adjucent to the foundation,different thickness of the thin layer element and the influence of the number of element layers dividing the dam body in the radial direction on the dam stresses obtained have been studied,the principle of grid division for Xiluodu Arch Dam has been determined.The calculation results indicates that division of the dam body adjucent to foundation into thin layer element greatly improves the obtained dam stresses at the edge and a stable finite element analysis numerical solution can be obtained.
