Abstract

Shield excavation technology is widely used in subway tunnel construction. There are complex risk factors in the process of tunnel excavation, and there is a certain correlation between them. The traditional reliability analysis is difficult to characterize the coupling relationship. In this paper, the Copula theory can accurately describe the characteristics of the correlation between parameters, and build the joint distribution function between support pressure and surface settlement. The correctness of this method is verified by engineering examples. Finally, the results show that the Frank function of Archimedean Copula with single parameter is the best Copula function. It can well characterize the joint distribution function between support pressure and surface settlement, and realize the random simulation more accurately. Combining with Monte Carlo simulation, more reasonable reliability results can be obtained. There is a strong negative correlation between the two parameters, neglecting this negative correlation will overestimate the failure probability of the parameter.
