In order to study the optimal design scheme of the section width parameters of Yangzhuang Gate pier reinforcement, the stress and displacement characteristics of the design scheme were calculated and analyzed by Abaqus. The results show that the maximum tensile and compressive stresses are the inner side of the pier body and the connecting beam respectively. The maximum tensile stress of the inner and outer side of the pier body is the relationship of inhibition and promotion in the section width parameters of 0.5~2 m and 2~3 m, respectively.However, the influence characteristics of the maximum compressive stress in these two intervals are the relationship between promotion and inhibition, that is, the tensile and compressive stresses of the scheme with a width of 2 m are the lowest and the largest. The maximum tensile stress and Z-direction negative displacement of the connection beam are less affected by the width parameters, while the maximum compressive stress is stable at 11.8 MPa before the width of 2 m, and decreases after the width exceeds 2 m. Comprehensive analysis shows that the optimum design scheme is the section width parameter of 2 m.
