After over 30 years of fast economic development and massive construction of
infrastructures, China now owns the largest total length of tunnels in the world. However …

The provision of real-time and detailed evacuation information feedback is vitally significant
for the formulation and adaptation of the onsite evacuation strategy. The conventional …

A major fire disaster is hazardous to both occupants trapped in the built environment and
firefighters during the firefighting operation. Though various construction codes …

This paper presents evacuation simulations of occupants' flow in a tunnel fire via a modified
cellular automaton model and puts forward corresponding optimized evacuation strategies …

UHPC is becoming a promising repairing material. However, little attention is paid on the
effect of the chloride attack on the bonded system repaired by UHPC. In this study, UHPC …

In the event of fires and other hazards, visual guidance systems that support evacuation are
critical for the safety of individuals. Current visual guidances for evacuations are typically …

The number of urban tunnels has been increasing rapidly, accompanied by frequent tunnel
fire accidents owing to the complex tunnel structure and large traffic flow. In this study, a full …

The vehicle collisions, intense heat radiation and convection from flame and high-
temperature smoke can easily cause double-source fire disasters in tunnels. In this paper …

This study proposes a framework integrating tunnel fire knowledge with the machine
learning approach to provide key fire parameters and reconstruct tunnel fire scenarios. The …

Pipe jacking has been the dominant trenchless technology for constructing small (< 2 m) to
medium-diameter (< 4 m) tunnels. Uncertainties and construction difficulties increase …
