中文摘要：

准确把握火灾产物对地铁车站中人员疏散速度的影响是地铁车站消防和疏散设施布置的基础,已有研究忽视了地铁环境与一般建筑物环境对疏散人员的影响差异。本文选取典型的岛式地铁车站,利用火灾仿真软件Pyrosim标定了能见度、烟雾浓度（主要指CO）、烟气温度等火灾产物对人员疏散速度的影响,并与一般建筑物火灾条件下的结果进行比较。结果表明：地铁复杂环境下,能见度对人员疏散速度影响呈非线性关系而非一般建筑物环境下的线性关系,而CO浓度和烟气温度对人员疏散速度影响的函数结构形式没有变化,但参数变化明显。

英文摘要：

The influence of fire accidents on the speeds of the pedestrian evacuation in complicated subway environment has a significant impact on the configuration of subway fire-protection facilities as well as subway evacuation facilities. In most of previous research, the environment difference between subway stations and regular buildings is usually ignored This paper regards a subway station as an island platform, and uses a software package called Pyrosim to establish the simulation model. The functions, which describe the impacts of fire product including the visibility, smoke toxicity （CO） and size of fire on pedestrian evacuation speed, are given. The results from subway station and general building environments are compared. The analysis shows that the visibility of evacuation speed is nonlinear in a complex subway environment rather than a linear relationship in the general building environment： function of CO concentration and smoke temperature influence on evacuation speed is unchanged but the parameters changed significantly.
