Abstract

With the rapid development of the social economy, the traffic volume has also shown a rapid growth momentum, which leads to the increasing load on the bridge, coupled with the corrosion and damage of the old bridge and the low limit of the original design load, so the general bridge capacity is insufficient. The problem began to appear. Traffic volume, increased vehicle load capacity and bridge damage have become increasingly prominent. The bridge is the throat to ensure the smooth flow of traffic. The key lies in the bearing capacity and transportation capacity of the bridge. The lack of bearing capacity of the bridge is the key to limiting the traffic capacity of the road. Therefore, it is an urgent and important task in the road traffic field to accurately evaluate the actual bearing capacity of the bridge and to choose a reasonable and effective method to strengthen the old bridge to ensure the normal operation of the bridge from the economic and social benefits.
