“…Many studies have been conducted on the steel corrosion of RC segments in salt-affected environments and on the behavior of chloride ions in concrete. However, few studies [2] have examined the effects of deterioration caused by chloride ions on the mechanical behavior of segmental joints.…”

“…In the previous stage of development [1,2], the purpose was to demonstrate the possibility of driving a railway vehicle using traction equipment such as a FC unit, a Bat unit and power converters. During this first stage therefore, the traction equipment was installed in space usually occupied by passengers because of the size of the equipment, and the acceleration performance was limited to that of DMU (approximately 0.4 m/s 2 ).…”

Deterioration caused by chloride ions may occur in some shield tunnels located in waterfront areas or near tidal rivers. In this paper, we propose a three-dimensional finite element analysis method for the maintenance of shield tunnels affected by chloride ions. In proposing this method, we developed a modeling method for deteriorated segment joints by reducing stiffness. In addition, we verified the validity of the method by loading tests of segmental lining specimens.
