摘　　要：以新疆齐古水库导流洞后消力池高、薄挡土墙为研究对象,借助ABAQUS软件对其加固方案进行有限元分析和比选,得到最优的拉杆布置形式。分析结果表明:消力池大部分部位为受压状态,局部拉应力区控制在规范允许范围内,拉杆支撑后结构应力分布均匀,变形量不大,满足设计要求,为解决实际工程中结构加固问题提供了参考依据。ABAQUS simulationbased 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.
