    摘要:Based on analysis of the normal and shear characteristics of the longitudinal joints in aging concrete gravity dams, the constitutive model of longitudinal joint is provided, especially a new normal constitutive function is developed reasonably for elements with thickness simulating such joints, and then all the ideas are written in the nonlinear finite element code including increment iteration method. The non-balance force at each node and the normal penetration of the two interfaces of each joint element are adjusted simultaneously by utilizing the code. The testified examples prove that it is reliable, precise and general. Furthermore, an actual aging gravity dam with longitudinal joints is numerically simulated, and the variation of the deformation and stress distribution of the dam are definitely analyzed by modifying different key mechanical parameters of the joint elements. So the new idea in this paper is practicable and can be applied for similar project problems.
