公路桥梁在400T级荷载下加固技术的探索

Inquiry on highway bridge reinforcement technology under 400T-grade load

通过对超限车对高速公路桥梁造成损坏的角度进行分析,从桥梁加固设计、施工、监测、安全条件四个方面进行了论述,提出了不进行处治,会对桥梁造成不良后果的观点,解决了400T级超限车安全通过的问题,达到了为今后同类问题提供借鉴的效果。

Through analyzing impact of over-limit vehicle upon highway bridge,starting from four aspects of bridge reinforcement design,construction,monitoring and safety conditions,the paper discusses and puts forward bad effect upon the bridge without treatment,and solves400T-grade over-limit vehicle driving safety,so as to provide some guidance for solving similar problems in future.
