The purpose of this study is to ensure the safety operation and maintenance utility tunnel. First all, framework management system in phase tunnel constructed by combining BMI technology, Access database tool integrates data with BIM technology establish a BIM-based database. On basis, model an using Autodesk Revit modeling software. Finally, application visualization, education fire simulation...

With the continuous expansion of urban cable scale and increase in service time, fire accident risk tunnels also increases. Defects configuration prevention measures lead to many accidents seriously affect reliability power supply. First, detection data a typical tunnel are analyzed this study. The results show that main problems unreasonable installation position extinguishers, lack between in...

There are many kinds of public transportation systems, e.g. Xue-shan tunnel, high-speed railway, and airport shuttle are developed in Taiwan recently. The risk hidden in the space of long road tunnel could cause serious life loses and transportation system damage. Therefore, how to prevent and decrease the impact of disaster should be considered for the disaster precaution and security manageme...

The tunnel is one of the most important components in modern underground engineering. Due to long and narrow shape constraints, it very easily results large-scale fire explosion when deflagration caused by accidents vehicles that transport dangerous goods tunnel. Previously, studies on damage lining high-temperature impacts these kinds disasters were often limited a discussion only influencing ...
