地铁长区间隧道火灾工况风速实测情况分析

Analysis of the Actual Measurement of Wind Speed in a Long Subway Tunnel under Fire Conditions

检验隧道通风系统功能有效性的重要标准就是对区间风速进行实测,而且实测数值应满足相关标准、规范的要求。结合某地区地铁开通运营前消防验收对地下区间火灾工况风速的实测情况,对长大区间实测风速结果进行了介绍及分析,总结了实测时需注意的事项,并分析了影响测试结果的重要因素,以期为后续线路区间风速的测试提供一些指导。

An important criterion for testing the effectiveness of the tunnel ventilation system is to measure the interval wind speed,and the measured value should meet the requirements of relevant standards and codes.This article combines the actual measurement of wind speed during fire conditions in the underground section of the subway before the opening of operation,introduces and analyzes the results of the measured wind speed in the long-distance section,summarizes the points to be noted during the actual measurement,and analyzes the influence of the test results important factors,which provides some guidance for the follow-up line section wind speed test.
