轨道交通工程人防通风设计思考
Study on ventilation design for civil air defense of rail transit
摘要：
结合实际工程，阐述了轨道交通工程人防通风设计思路。针对不同防化等级，给出了战时通风量的计算方法。对战时通风系统进行布置，对比2种滤毒通风布置方式并提出了建议。对平战转换内容进行了说明，指出防护处理方法和管道设计的问题，为轨道交通工程人防通风设计提供了参考范例。

Abstract：
Combined with an actual project, elaborates the design ideas of civil air defense ventilation of rail transit. Focusing on the different grade of nuclear, biological and chemical (NBC) protection, proposes a calculation method of ventilation rate in wartime. Carries out a layout of wartime ventilation system, compares two gas filtration ventilation layout methods and provides suggestions. Explains the conversion of peacetime and wartime, and points out the protective treatment methods and problems in pipeline design. Provides a reference for civil air defense ventilation design of rail transit projects.
