| 摘 要： | 地铁高架车站的人员安全疏散设计的原则是首先需要满足《地铁设计规范规》的要求,同时也要满足火灾工程学的安全疏散要求。本文首先介绍了地铁高架车站人员疏散通道的性能化设计过程和方法。选取广州地铁四号线典型高架车站,采用火灾场模拟和人员疏散动力学模拟的方法,计算模拟高架车站的站厅火灾时的烟气蔓延过程,以及高架车站的人员疏散过程。研究指出现有的通道设计能够确保在火灾时人员能够安全疏散。计算过程和方法可为国内地铁高架车站的人员疏散设计提供参考。

| Abstract: | The design of occupant evacuation for the elevated metro station should accord with not only Code for Design of Metro,but also the fire engineering safety demand.The paper firstly introduces the performance-based method for the design of the evacuation passway of the elevated metro station.Then an elevated metro station of the Guangzhou Line 4 have been taken for the case study.Based on CFD modeling and agent-based evacuation method,the smoke spread and occupant evacuation process have been simulated,indicating the current passway design can assure the safety evacuation in fires.The calculation method can been applied as reference for the passway design of such elevation station. |
