Research on Load -bearing Capacity of Partly Repaired RC Segments
Abstract: Segmental tunnel linings constructed in the ground near the sea need attention with regard to the deterioration of reinforced concrete segments caused by salt damage. For segments seriously affected by salt damage, a repair method that replaces part of the deteriorated segments with a new material to recover its durability is used. However, the effect of this method on the load-bearing capacity...

Study on Section Repair Method for Cut and Cover Tunnels
Abstract: Tokyo Metro currently maintains 196km of structures with 9 routes, of which approximately 85% are tunnels. As a daily repair against deformation such as freaks and leakage of tunnels, cross-section repair is commonly used. However, methods and materials of crosssection repair have been used for many years without being updated. So, to introduce a method using the latest technology and...
