| 要旨 | During the life-cycle of an underwater shield tunnel, the long-term performance of the segmental linings will be affected by mechanical and environmental stressors, such as high water-soil pressure and aggressive agents. Therefore, the structural performance of a tunnel will deteriorate with time after its construction is completed. This paper investigates the damage process of segmental specimens under different load levels in an aggressive environment based on experiments of corrosion-accelerated specimens of a tunnel segment. In addition, an estimation method for determining the deteriorating damage of segmental linings is proposed. |
