Abstract

Abstract

The concrete durability failing with time model(CDFT Model)is used to forecast the service-life of different segments used in the Wuhan Yangtze River tunnel project.The result shows that taking different influencing potential factors into account,the service-life of functionally delaminating system with high impermeability,long service-life and large diameter segment of shield tunnel(HILS)can reach 150 years with the most conservative estimate.And the chloride ion diffusivity is simulated based on finite element method.the result shows that the resistibility towards chloride ion diffusivity of functionally graded system segment is much better than that of composite cementitious material system.
