纪念隧道火灾通风试验计划的很大一部分用于确定各种抽气试验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。受控火灾位于2800英尺（853米）长隧道的大约四分之一处，强度有两个级别:20和50MW。共进行了17次单点排气试验和5次超大排气口试验，均采用单区部分横向结构。单点提取测试使用了火灾北部和南部的100、200和300平方英尺（9.3、18.6和27.9平方米）的点开口。超大排气口测试采用了易熔板和易熔线阻尼器。根据获得的数据说明从这些测试中得出的结果和结论。单位:双关键字: 1997年，烟雾通风，隧道，测试，火灾，美国，换气率，性能，道路交通:研讨会，ASHRAE交易，第103卷，第2部分，波士顿1997

A significant portion of the Memorial Tunnel Fire Ventilation Test Program was devoted to determining the effectiveness of various extraction tests 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 2,800 ft (853 m) long tunnel, was varied at two levels of intensity: 20 and 50MW. A total of 17 single-point extraction and 5 oversized exhaust port tests were conducted, all in a single-zone partial transverse configuration. The single-point extraction tests utilised 100-, 200- and 300-ft2(9.3-, 18.6-, and 27.9-m2) point openings both north and south of the fire. The oversized exhaust port tests applied fusible panels and fusible link dampers. Addresses results and conclusions drawn from these tests on the basis of acquired data.Units: DualKEYWORDS: year 1997, Smoke ventilation, tunnels, testing, fire, USA, air change rate, performance, roads
