Abstract

In the highway tunnel construction project, the secondary lining cracking is one of the most common diseases, needs to analyze the reason thoroughly, to clarify its own mechanism, can propose the relatively effective measure from the source. In this paper, the internal force of the lining of a highway tunnel during construction is mainly based on the engineering geological conditions, hydrological conditions, design conditions and so on, this paper analyzes the cracking problem and the cause of settlement deformation, and puts forward some effective treatment measures to prevent the cracking and settlement deformation of the second lining, it can also provide useful experience for other projects.
