| 摘 要： | 火灾是城市地下空间内令人倍受关注的灾害问题,对火灾发生情形下的人员疏散及救援等问题进行研究,显得非常必要。本研究进行基于风险理论指导下的火灾疏散技术研究,将火灾发生情形下的风险制定为四级,分别为:可忽略的、稍加关注的、严重的与灾难性的,并进行基于2级火灾风险等级反向设计地下空间逃生结构。运用buildingEXOUDS专业疏散软件对发生于地下空间内的火灾风险事故进行模拟,以某隧道为例,对联络通道式结构间距进行优化设计,得到结论:在通风速度为3.0m/s情形下,联络通道间距设计为100m以下时,能满足火灾时的安全疏散,并指出这样的疏散方式所构成的风险等级,虽然是可被社会接受的。

| Abstract: | Fire in the underground space is a serious accident.It's very essential to study the evacuation technique and how to rescue people in the fire situation of underground space.The authors studied the fire evacuation technology based on risk theory.In the article,4 fire risk grades have been given,that is:1.fire risk,which can be ignored,2.fire that needs attention,3.serious and 4.disastrous.Then,the authors designed an optimization tunnel escape structure based on 2nd grade fire by CFD technology to simulate ... |
