摘要:
基于有限元理论,借助通用计算程序ANSYS对一实桥建立有限元模型,结合检测结果,分析了该桥在不同荷载工况下挠度、应力、自振频率以及振型特征的变化趋势,研究了加固前后桥梁结构的静、动力特性.结果表明:锚喷混凝土加固小铰缝板桥有效地降低板梁截面的应力和应变,提高桥梁结构的自振频率.由此可知,锚喷混凝土加固可提高结构的整体刚度,增强结构的抗弯及抗扭能力,改善桥梁整体受力特性,具有较高的推广应用价值.
Abstract:

Based on the finite element theory, with the help of the general calculation program ANSYS, a finite element model was established for a solid bridge, and the changes of deflection, stress, self-resonance frequency and mode shape characteristics of the bridge under different load conditions were analyzed based on the detection results, and the static and dynamic characteristics of the bridge structure before and after reinforcement were studied. The results show that the anchor sprayed concrete reinforcement of the small hinged slab bridge effectively reduces the stress and strain of the section of the plate girder and improves the self-resonance frequency of the bridge structure. It can be seen that the reinforcement of anchor sprayed concrete can improve the overall rigidity of the structure, enhance the bending and torsion resistance of the structure, and improve the overall force characteristics of the bridge, which has high promotion and application value.
