| 摘 要： | 以打山渡槽加固工程为实例，采用有限元方法建模分析求解，计算不同工况下的内力和变形，进而判断各个薄弱截面承载力是否满足设计要求。计算结果表明，打山渡槽主体受力结构安全性满足相关规范要求，利用该方法为此类大型渡槽结构受力计算分析提供了借鉴。

| Abstract: | Taking the reinforcement project of Dashan aqueduct as an example, the finite element method is used to model, analyze and solve, calculate the internal force and deformation under different working conditions, and then judge whether the bearing capacity of each weak section meets the design requirements. The calculation results show that the safety of the main stress structure of Dashan aqueduct meets the specification requirements. This method provides a solution for the stress calculation and analysis of this kind of large aqueduct structure. |
