A resilience assessment
approach is proposed for the construction safety of urban underground
engineering adjacent to an operating metro. First, three key factors involved
in close construction (existing underground structure, formation, and newly-built underground engineering) and two dimensions (technology and
management) are analyzed, establishing a relatively complete resilience index
system. Second, a weight combination analysis approach for the resilience index
system is developed using the analytic hierarchy process, entropy weight
approach, and game theory. Furthermore, a method for the continuous evaluation
of the complex performance Q of the system is proposed based on the theory of set pair analysis.
Finally, an evaluation formula for resilience R is proposed from the aspects of maximum damage and cumulative
damage, which is then applied to the analysis of a case study. The main
findings include: (1) The newly proposed resilience assessment method can be
mutually verified with traditional risk assessment method, and the new method
considers more comprehensive factors. (2) The composite performance Qof the proposed system contains three
dimensions, namely, existing underground structure (QA), formation (QB), and newly-built underground engineering
(QC),
showing more comprehensiveness than the conventional assessment theory. (3) As
the limits of dynamic indices of existing underground structures become increasingly
stringent, the evaluation results of the system's composite performance Q correspond to a decrease.
