During subway operation, cracks may appear at the arch waist of tunnel segment surface. Under the acceleration of stray current, chloride ion in groundwater will penetrate into the surface of rebar through cracks, resulting in segment rebar corrosion and structural stiffness degradation. In this article, the rebar corrosion calculation model of tunnel segment contained transverse crack under stray...
Corrosion of the steel rebar will be generated in the cracked concrete of the shield tunnel during the operation period, which will reduce the bending performance of the tunnel segment. In this study, the effect of the rebar corrosion on the bending deflection of the shield tunnel segment that contains transverse cracks is investigated by experimental tests. The initial transverse cracks of the segment...
