The evacuation and rescue is a key problem in the
operation of largediameter shield tunnel. First, based
on the operation safety characteristics of tunnel, the characteristics of tunnel
safety accidents and evacuation and rescue are analyzed. Second, through case
analysis and data demonstration, the principles and standards of evacuation and
rescue are preliminarily discussed, and the standards of evacuation time (no
more than 6 min) and rescue time (no more than 15 min) are proposed.
Recommendations are present from the aspects of fire fighting and control and
medical rescue of highway tunnel, especially for those without clear rescue
standards. Finally, the recommended principles and standards are applied to
conduct a special evacuation and rescue scheme with a case study of extralong shield tunnel on east Liuhuan road in Beijing under
construction based on theoretical research. The effectiveness of the scheme is
verified using numerical simulation method. With the development of highway and
urban roads, there will be more and more complex tunnels such as extralong tunnel, extrawide tunnel, and
bifurcated tunnel, resulting in increasing pressure of tunnel operation, which
demonstrates that safety design should be carried out from the perspective of
management.
