Safety Analysis of Concrete Arch Dam Considering the Shear Action of Contraction Joints
In this paper, taking an extra-high arch dam as an example, the simulation of the stress, deformation and overload failure of arch dam is carried out to investigate the effect of the shear strength of contraction joints on the safety of the arch dam based on the nonlinear trial load method. The numerical simulation results show that the overload safety factor of the arch dam decreases significantly with the decrease in shear strength of contraction joints. The maximum tensile stress of the arch dam is reduced when the shear strength of the contraction joints is reduced by 30% compared to the strength of the dam material. The results provide a reference for the design of the mechanical properties of the contraction joints.
