Abstract:
This paper selects carbonization models available as prediction models of subway concrete carbonization deepness in order to compartment different parts metro concrete carbonization environment in China through texts for carbonization environment and situation of concrete structure in Nanjing metro line 1. The result verifies the adaptability of existing carbonization models. It attains the goal on the condition of 10% probability of failure by using Monte-Carlo method. The result shows that the carbonization of subway concrete in north China is much more serious and the carbonization life is less than 70 years while it is more than 120 years in southwest China.
