STUDY ON STRUCTURE PERFORMANCES DEGRADATION OF SEGMENTAL LINING OF SHANGHAI YANGTZE RIVER TUNNEL

摘要：

In the coast or the marine environment,the chloride erosion is the main factorscaused reinforcement corrosion of tunnel lining. First,according to the basic principles ofelectrochemical method for the accelerate reinforcement corrosion,and taking the ShanghaiYangtze River Tunnel as research background,An interior test are made on the accelerationof reinforcement corrosion in the segment of shield tunnel,and a set of experiment componentwith the different corrosion degree is got; Second,the bearing capacity,deformation,ductilityand damage characteristics of the corrosion component are tested,the degradation regularityof structure behavior of tunnel lining in the environment of chloride erosion are analyzed andsummarized. In conclusion,the results have an important reference in the prediction of servicelife and the durability design for tunnel lining.
