在多座实桥加固基础上,提出双曲拱桥加固新方法—异型截面拱加固法。首先对加固思路、加固方法和力学机理进行详细阐述,在此基础上,利用有限元数值分析工具ANSYS和数学统计方法,对该加固方法做进一步优化设计和比较分析,确定最优方案。最后,通过实桥加固与优化详细介绍了异型截面拱加固法的运用过程。
Based on the reinforcement of several solid bridges, a new method of reinforcement of double curved arch bridges is proposed, that is, the special-shaped cross-section arch reinforcement method. First of all, the reinforcement ideas, reinforcement methods and mechanics are elaborated. On the basis of this, further optimization design and comparative analysis of the reinforcement method are carried out by using the finite element numerical analysis tools ANSYS and mathematical statistics to determine the optimal scheme. Finally, through the reinforcement and optimization of the real bridge, the application process of profiled cross-section arch reinforcement method is introduced in detail.
