Assessment of health condition and management system for road tunnel by inspection data in Japan

A comprehensive evaluation method and application of shield tunnel structure health based on variable weight theory

“…Relevant indicators for the safety evaluation of shield tunnel structures involve various standards and norms in China (CJJ/T 289-2018, 2018; Bergeson and Ernst, 2015; Eskesen et al , 2004). The corresponding reference indexes and classification standards have been proposed for the leakage rate, curvature deformation limit, crack opening, judgment standard of lining strength, misalignment, void and track bed (Andreotti et al , 2020; Kimura et al , 2019; Tichý et al , 2021). Among them, qualitative indicators are determined by a ten-point scoring method.…”
