Abstract: ABAQUS simulation-based optimization for reinforcement of high and thin retaining wall was adopted in the case of stilling basin side-walls behind the diversion tunnel of Qigu reservoir in Xinjiang. The best solution using bars strengthening was obtained. The results showed that most parts of the stilling basin was in compression state, the value of local tensile stress was controlled within the allowable range of the Specification, stress distribution of the structure became uniform, and the deformation was reduced. This method provided a reference for solving structural reinforcement in practical projects.
