Abstract Multiple structural planes are found at the abutments of Wudongde arch dam. It is important for dam compatible deformation to ensure dam overall stability safety. Based on 3D nonlinear finite element，the effect of structural planes on the working performance and stability of Wudongde arch dam is analyzed. The reinforcement effect is discussed from the view of stress homogenization，compatible deformation and stiffness matching. The results show that under the influence of structural planes，the transverse displacement at the abutments increase obviously and local foundation rock deform incompatibly close to structural planes，as well as present stress concentration and local plastic zone. The reinforcement measures，i.e. consolidation grouting and concrete replacement，are able to improve the distribution of stress and deformation. The proposed compatible reinforcement procedure is a valuable tool for improving the reinforcement design and analysis of similar super high arch dams.

Key words： hydraulic engineering super-high arch dam abutment structural plane compatible reinforcement
