[VI-543] Point of inspection management of the Tunnel method supported by sheet pile
Keywords:the method supported by the sheet piles, inspection management, deterioration, Road tunnel
At present, NATM is the standard construction method for tunnel construction. The previously built tunnels were constructed using a method supported by sheet piles. Most of the expressway tunnels more than 30 years after construction were constructed using the method supported by the sheet piles. Many of the engineers who currently maintain the tunnel have no experience in constructing the tunnel by the method supported by the sheet pile. Therefore, knowing how the tunnel was made is necessary to consider the repair method. In this report, it is explained in which part the tunnel constructed by the method supported by the sheet pile is deformed.
