Comparison and selection of evacuation exit methods for a subway tunnel

结合杭州环城北路地下通道工程疏散通道的设置方案,分析不同疏散方案的优缺点,参照国内外现有的工程案例,并考虑不同方案的隧道建设风险和建成后的运营风险、疏散能力以及建设的经济性要求等,确定适合此工程的合理的疏散通道设置方案,以期为类似工程的疏散通道设置提供指导。

Based on the highway tunnel project under Northern Ring Road of Hangzhou, the advantages and disadvantages of different evacuation plans were analyzed. Compared with the existing projects both at home and abroad, the final reasonable evacuation exit design method was determined considering the risks during construction stage and servicing stage, the requirements of building economy, and the evacuation capability. The above characteristics should be considered during the design of evacuation routes in the future.
