Abstract: This paper adopts FLAC3D software based on 3D fast Lagrangian method to calculate the deformation and stress of Wanjiakou High RCC Arch Dam.The water-level overcharge method is used to simulate the gradual destruction process andunstabilization model of the arch dam and base system.The results show that thedeformation and stress of Wanjiakou High Arch Dam and base can meet the standard requirement.The overall stabilization safety degree of the system is 4.0 and canmeet the design requirement.The limit loading capacity of the arch dam and basesystem is commonly controlled by the strength of Ⅳ class rock in the dam heel,the unconformity surface and the joint groups in left bank abutment.

Key words: stabilization safety degree, fast Lagrangian method, FLAC3D, water-level overcharge method, Wanjiakou high arch dam, deformation, stress
