基于联合截面的圬工拱桥最小加固层分析

Analysis on Minimum Reinforcement Layer of Masonry Arch Bridge Based on Joint Cross Section

为了快速确定圬工拱桥最小加固层的厚度,评估加固后圬工拱桥原拱圈的应力状态,通过采用Midas Civil中的施工联合截面模拟新旧拱圈之间的黏结,计算组合截面的应力。最终通过对比不同加固层厚度下的原拱圈应力,确定最优加固层厚度,为圬工拱桥的加固以及加固效果的评定提供参考。

In order to quickly determine the thickness of the minimum reinforcement layer of the masonry arch bridge, the stress state of the original arch of the reinforced bridge was evaluated. The stress of the joint section was calculated by simulating the bond between the old and new arches using the construction joint section in Midas Civil. Finally, the optimal thickness of the reinforcement layer was determined by comparing the stress of the original arch under different thicknesses of the reinforcement layers, which provides reference for determining the thickness of the reinforcement layer of the arch bridge and evaluating the reinforcement effect.
