At the same time, there are more and more highway vehicles, which brings certain challenges and difficulties to the operation process of highway and bridge. In highway bridge engineering, there are many types of highway bridges, and the construction difficulties of different types of bridges are different. When the highway bridge is open to traffic for a period of time, with the continuous influence of traffic load, coupled with the interference of climatic environment, human factors and other conditions, diseases will inevitably occur in various structures of the highway bridge, and the bearing capacity of the bridge will gradually decrease over a long period of time, affecting the safety and stability of the highway bridge project. Therefore, it is necessary to carry out the necessary testing for the insufficient bearing capacity of the highway bridge and formulate effective reinforcement measures. In this paper, a series of reinforcement measures are proposed to solve the related problems of insufficient bearing capacity of highway bridges and are applied in specific projects.展开更多

In the construction process, cable laying is an important link. Due to the hidden nature of the cables, if you want to improve the laying effect, you must improve the engineering quality, make good preparations and select the appropriate site, so as to better improve the construction technology level.展开更多
