| Abstract: | Taking the Beijing subway tunnel shield configuration as the research object, the fire dynamics simulation software is used to calculate. Under different conditions, the detection simulation is carried out respectively for the different heat release rate of fire. Through calculation results, the increasing rule of temperature with the time in different position is summarized, and the analysis of the harmfulness of different locations in different time periods is provided as reference for safe escape. |
