Technical and economic analysis of ventilation and smoke exhaust plan for underground passageway in Beijing Olympic Culture Business Park
摘要：
针对北京奥体文化商务园区地下交通联系通道工程，从技术角度分析了多点地面直排式全横向通风方式、分段纵向通风方式、传统全横向通风方式3种通风排烟方案的安全性及有效性，从经济角度分析了各个方案的初投资及年运行费用。结果显示，多点地面直排式全横向通风方式可满足安全和环保要求，初投资和运行费用较低，可在城市隧道通风排烟中推广应用。
Abstract：
For the underground passageway project, technically analyses the safety and effectiveness of three kinds of ventilation and smoke exhaust schemes including multi-point ground direct discharge type transverse ventilation mode, sectional longitudinal ventilation mode and traditional transverse mode, and economically analyses their initial investments and annual operating costs. The results show that the multi-point ground direct discharge type transverse ventilation mode can meet the requirements of safety and environmental protection, and the initial investment and annual operating cost are lower, which can be used in ventilation and smoke exhaust system of city tunnels.
