Analysis of Three-dimension Finite-element Computation on Large Masonry Grav ity Dam

The variable modulus of elasticity and material variation problems are existing in masonry gravity dam of lower reservoir of Baoqunan pumped-storage power plant.Use the three-dimension finite element method to research the lay out of dam stree and displacement,and analyze the stress of dam heel,dam toe and deformation,then get the layout of dam stress.The result indicates that the gr avity dam is safe and totally to meet the standard.All this will porvide necessa ry data for the design of the similar project.
