桥梁作为公路的一个重要构成部分,随着我国交通量与行车密度、车辆载重的逐年增加,一部分公路桥梁因为耐久性较差和年久失修而威胁到过往车辆和行人的安全。由此可见,公路桥梁的加固工作已变得愈来愈重要。通过公路桥梁的加固,能够延长公路桥梁的使用寿命,从而满足当前交通流量之要求,并且减缓对桥梁进行投资之集中性。分析了公路桥梁加固的基本特点和技术要求,阐述了公路桥梁加固中存在的问题,并提出了公路桥梁加固的主要方法。
As an important part of the highway, as a bridge, the traffic volume and traffic density of our country and the load of vehicles increase year by year. Some of the bridges and bridges are threatening the passing of vehicles and pedestrians because of their poor durability and disrepair. This shows that the reinforcement of highway bridges has become increasingly important. Through the reinforcement of highways and bridges, the service life of highways and bridges can be prolonged so as to meet the current demands of traffic flow and reduce the concentration of investments in bridges. The basic characteristics and technical requirements of highway bridge reinforcement are analyzed. The existing problems in highway bridge reinforcement are expounded, and the main methods of highway bridge reinforcement are proposed.
