In existing
highway tunnel management systems, issues related to confusion among personnel
responsibilities, low efficiency, and high false alarm rates are encountered.
To address these issues, the "emergency fire protection" and "inspection and maintenance" functions of the tunnel management station
are assigned to a small and lightweight onsite
comprehensive station and a novel management system is proposed. In addition,
the fire safety of the novel system is assessed using a multilevel Monte Carlo
sampling algorithm. In particular, five maturity levels of fire safety are formulated.
A structural hierarchy analysis diagram for firesafety
evaluation is constructed based on four firstlevel
safety evaluation indicators, nine secondlevel safety
evaluation indicators, and 20 observation variables. Furthermore, the
probability and statistical characteristics of the 20 observed variables and
Monte Carlo sampling algorithm are analyzed. Finally, the firesafety levels of the novel and traditional systems are compared. The
evaluation results show that the firesafety levels of
the novel system are more reliable than those of the traditional system,
indicating that the proposed system outperforms traditional counterparts.
