摘　　要：近年来大型设备逐渐增多,且其重量远远超过了桥涵的设计荷载。为了使特种车辆安全通过沿线的桥涵,基于多点支撑原理,提出在桥涵下部增设支撑点,通过调整支撑点位置来改变桥涵的受力情况。通过分析桥梁加固前后的内力,证实了此加固方法加固效果明显,可为类似工程提供参考。In recent years, the number of large equipments is gradually increasing, and their weights are far more than the bridge design load. In order to make the special vehicle go through the bridge safely, based on the principle of multi-point support, the article proposes to add support at the bottom of the bridge, mediate the support position so as to change the stress state of the bridge. By comparing the bridge internal forces before and after reinforcement, the results show that the reinforcement effect is obvious, and the reinforcement method can provide reference for similar projects.
