ABSTRACT = {Existing studies on the durability of subsea tunnel mainly focus on the
concrete deterioration and steel corrosion, while there are few on the influence of
mechanical properties deterioration of surrounding rock on the durability of subsea tunnel. To improve the accuracy of long-term stability prediction, seawater
corrosion tests of intensely weathered surrounding rock of subsea tunnel are carried out. In this study, the strength characteristics of remolded samples of intensely weathered granite under different seawater concentrations are investigated,
the strength attenuation equation under seawater corrosion is established, and
the chemical damage evolution equation and model parameters are formulated,
The findings provides the basis for analyzing the influence of corrosion and weakening of surrounding rock on the durability of tunnel within the operation period.},
