<p>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.</p>
