Abstract: In recent years, with the development of bridge and tunnel, China's transportation network is becoming more and more perfect. In the construction of bridge and tunnel projects, bridge and tunnel construction is more dangerous than other projects. Therefore, the overall construction quality and efficiency of the project and the safety of personnel should be considered in the construction. The construction must be combined with topographic conditions to ensure waterproof and anti-corrosion treatment, and ensure the stability and safety of bridge and tunnel engineering operation. However, many engineering construction will lead to various problems due to improper technology application, management problems and material use problems. Based on this, this paper analyzes the common problems in bridge and tunnel construction, and puts forward some suggestions to strengthen bridge and tunnel construction technology and management control.
