- STUDY OF MAINTENANCE OF SHIELD TUNNEL FOR UNDERGROUND TRANSMISSION
抄録
In this report, the methods of management and maintenance of the shield tunnel for underground transmission cables were studied. These studies are based on the Performance-Based Design concept, and focused on the load bearing capacity of a tunnel. First, the maintenance cycle were reviewed for improving efficiency and effectiveness by considering the present inspection period and the soundness of a tunnel. For reviewing the maintenance cycle, the changes of load bearing capacity due to the changes of external loads and soundness caused by aged deterioration of segmental joints, and the criteria and the standardization of inspection results were investigated. Moreover, the corrosion speed and the fastening force of a segmental joint were inspected. The changes of external loads were assumed and used them for evaluating the load bearing capacity of a tunnel. The standard of an inspection was also reviewed based on the standards of deterioration materials, and the load bearing capacity obtained by structural calculation. Based on results of all investigation, the rational management and maintenance methods of a shield tunnel and the applying methods for existing tunnels are proposed.
