目前,我国有很多道路桥梁长期处于严重超负荷状态,其原因主要就由交通流量的递增所引起的,正是由于这个原因使得道路桥梁的结构性受到了很大的破坏,有的道路桥梁甚至成为了危桥。由此可见,重载道路桥梁安全性措施的研究,对我国道路交通安全稳定的发展具有重要的意义,是延长道路桥梁的使用寿命,提高我国交通管理水平的重要途径之一。本文通过对超载情况的考察总结出安全性的评定方法,并根据这些方法找出加固道路桥梁的主要措施。 At present, many roads and bridges in our country have been seriously overloaded for a long time. The reason is mainly caused by the increase of traffic flow. It is precisely for this reason that the structural nature of road and bridge has been greatly damaged. Some roads, bridges and even Become a dangerous bridge. Therefore, the study on the safety measures of overloaded roads and bridges is of great significance to the development of road traffic safety in our country. It is one of the important ways to extend the service life of roads and bridges and improve the traffic management level of our country. This paper summarizes the evaluation methods of safety by examining the overload conditions and finds out the main measures to reinforce the road and bridge according to these methods.
