| Abstract: | Aim at the gravity dam dynamical characteristic finite element method calculation on the reciprocity of dam-water-foundation, presented the compatible displacement method of incompatible mesh, which can be used for calculation of complicated structures of the foundations. By using the developed computer program, dynamical characteristic calculation of the gravity dam of Gutianxi first cascade was carried out and compared with the compatible meshes computed results, which verified the method to be reasonable. |
