Abstract

In order to analysis the vulnerability of underground deep foundation pit construction system and improve the safety level of underground deep foundation pit construction. Firstly, based on the vulnerability theory, the concept of vulnerability of underground deep foundation pit construction safety system is proposed; secondly, the three characteristic elements of vulnerability are used to construct a diagram of the recursive evolution process of vulnerability influencing factors; finally, a total of 107 underground deep foundation pit construction safety accidents are selected from 2010 to 2022, and the probability of each factor and its coupling value when coupling occurs in different cases are calculated using the N-K model to derive the key coupling factors affecting the vulnerability of subway deep foundation pit construction system. The key coupling factors affecting the vulnerability of metro deep foundation pit construction system. The study shows that: the probability of accidents and the number of factors involved in the coupling is positively correlated; through the vulnerability analysis can find the weak links of the underground deep foundation pit construction system, and provide certain theoretical support for improving the level of safety management of underground deep foundation pit construction.
