纪念隧道火灾通风测试项目的多项测试致力于确定全横向通风系统在不同系统配置和空气流速下限制烟雾和热气扩散的有效性。受控火势位于2800英尺（854米）长隧道的大约四分之一处，其强度有三个级别；10、20和50兆瓦（MW）。在整个道路的固定横截面位置和天花板上方的通风室内，高度绝缘的仪器“树”配备有热电偶、双向皮托管和气体取样管。 远离隧道的控制拖车中的数据采集系统（DAS）连续记录空气温度、空气速度和气体浓度，以供后续分析。闭路电视（CCTV）系统由隧道内的七个摄像头组成，紧邻隧道入口，便于在监控拖车内的监控器上观察烟雾运动。共进行了19次全横向试验，其中9次采用平衡送风排气流量，10次采用不平衡系统配置，其中排气流量超过强制送风流量，从而导致发生故障- 通过隧道入口引入空气。阐述了作者作为联合试验组成员见证这些试验所获得的数据和观察结果的基础上得出的结果和结论。单位:双关键词:1997年，测试，烟雾通风，火灾，隧道，美国，比较，道路科学:研讨会，ASHRAE交易，第103卷，第2部分，波士顿1997

A number of tests of the Memorial Tunnel Fire Ventilation Test Program were devoted to determining the effectiveness of a full-transverse ventilation system in limiting the spread of smoke and hot gases, with varying system configurations and air flow rates. The controlled fire, located at the approximate quarter point of the 2,800ft (854m) long tunnel, was varied in three levels of intensity; 10, 20 and 50 megawatts (MW). Heavily insulated instrument "trees" at fixed cross-sectional locations throughout the roadway and in the plenum above the ceiling were equipped with thermocouples, bidirectional pitot tubes, and gas sampling tubes. The data-acquisition system (DAS) in a control trailer remote from the tunnel continuously recorded air temperatures, air velocities, and gas concentrations for subsequent analysis. A closed-circuit television (CCTV) system, composed of seven cameras inside the tunnel and immediately adjacent to its portals, facilitated observation of smoke movement at the monitors, which were also located in the control trailer. A total of 19 full-transverse tests were conducted - 9 with balanced supply-exhaust air flow rates and 10 with an imbalanced system configuration in which the exhaust flow rate exceeded the forced supply flow rate, causing the make-up air to be introduced through the tunnel portals. Addresses results and conclusions drawn by the author on the basis of acquired data and observations as an eyewitness to these tests as a member of the joint test group.Units: DualKEYWORDS: year 1997, Testing, smoke ventilation, fire, tunnels, USA, comparing, roads
