Analysis on The Causation and Classification of Common Damages of Highway Tunnel
Highway tunnels involves various types of lining and various geological conditions. It is difficult to obtain sufficiently accurate information on geological conditions, and the existing tunnel design theories and the methods are not mature either. At the same time, the stresses of the tunnels during the stage of design, construction, operation and maintenance are also different. So it is difficult to determine the causes of the damages of tunnels because of the joint influence of the above factors. Through the overall investigations of various damages of highway tunnel and the analysis of the causes and patterns of the damages, tunnel damages have been classified. The causes of damages have been studied in respect of external forces, design, construction and the crack of materials for different types of highway tunnel problems. The experience can be used for reference and the similar damages an be avoided through precaution to improve the quality of design and construction. Additionally, the conditions of the structure can be evaluated scientifically on a theoretical basis. Effective measures can be taken to delay the process of damages and extend the lives of tunnels.
