地下车库联络道通风设计探讨

Discussion on ventilation design for underground parking links

通过介绍地下车库联络道这类新型城市地下道路的建筑特点,分析了地下车库联络道通风系统,特别是排烟系统设计的重要性。同时,结合现有国内规范和近年来国内地下车库联络道项目的实际情况,从地下车库联络道的建筑类别、火灾热释放率、通风方式、风道材质等方面对相关通风设计进行了探讨和分析,提出了国内地下车库联络道通风系统设计的相关建议,可为今后此类项目的通风设计提供借鉴。

This paper presents the architectural characteristics of the underground parking link which is a new type of urban underground road,and analyses the importance of the ventilation system design,especially the smoke exhaust system design for underground parking links.Meanwhile,combined with the existing domestic standards and the actual situation of the domestic underground parking link projects in recent years,the relevant ventilation design is discussed and analysed in terms of the building category,fire heat release rate,ventilation pattern and air duct materials of the underground parking link.The relevant advices about ventilation system design for the domestic underground parking link are put forward,which can provide a reference for the ventilation design for such projects in the future.
