摘要： 为研究更贴近真实火灾工况下的疏散行为，开展了居民楼有烟环境中人员沿楼梯上行移动特性的研究。实验中设置了无烟、轻烟和浓烟3 种不同的能见度工况。结果表明，烟气环境中，移动速度除仍受移动距离影响外，心理作用也是影响移动速度的重要因素。轻烟环境对人员的移动速度影响不大，而浓烟环境中，在心里恐慌作用下，加上能见度的影响，疏散人员会借助于楼梯扶手加快移动速度，上行的移动速度较无烟和轻烟环境更快。

Abstract: In order to study the evacuation behavior in a fire, a study on the moving behavior of the people walking upstairs in the smoke environment in residential buildings was conducted.Three different visibility conditions e.g. no smoke, light density of the smoke and dense smoke were set. The research results show that when the people walking in the smoky environment,besides the walking distance, the psychological effect is also an important factor for the movement speed. The light smoke environment has little effect on the moving speed of people. In the thick smoky environment with lower visibility, the people would be panic, and would walk faster with the help of the handrail.The upward moving speed is greater than those in the smokeless and light smoky environments.

Key words: smoky environment, stair, walking upstairs, evacuation, moving speed
