| 摘 要： | 应用有限元软件ANSYS，采用Solid65单元建立了斜腿刚架拱桥的三维仿真模型，并研究了外包混凝土加固法对斜腿刚架拱桥的应力滞后效应、二次受力性能及其对桥梁横向刚度的影响，研究结果表明，外包混凝土加固法有明显的应力滞后现象，但对斜腿刚架拱桥具有明显的加固效果，并且能增强桥梁的横向整体刚度。

| Abstract: | Based on the finite element software ANSYS,three-dimensional simulation model of the inclined leg rigid frame arch bridge is established according to the Solid65 unit,the stress hysteresis effect and the second stress performance of the surrounding concrete reinforcement process on the inclined rigid frame arch bridge,as well as the influences of it on bridge lateral rigidity are studied.Research results show that the surrounding concrete reinforcement process has obvious stress hysteresis effect,but also h... |
