桥梁支座在整个桥梁结构中对桥梁墩台的受力状态和梁的水平位移、转角起着十分重要的作用,其性能的好坏对桥梁的使用效果与寿命有直接影响。本文主要研究铁路桥梁支座出现的常见病害,并提出针对性的预防措施,从而解决影响桥梁结构安全性和耐久性的重要因素,预防事故发生。 Bridge bearing in the whole bridge structure on the bridge piers and the force of the horizontal displacement of the beam, the angle plays a very important role in the performance of the bridge has a direct effect on the use and life. In this paper, the common defects of railway bridge abutments are mainly studied, and some preventive measures are put forward so as to solve the important factors that affect the safety and durability of bridge structures and prevent accidents.
