【摘要】 隧道发生火灾时,及时准确地对火源点进行定位并做出响应对人员的疏散及消防活动具有重要意义。本文以两热源间辐射换热理论为基础,结合分布式光栅光纤火灾探测系统,推导出基于光纤光栅感温系统的火源定位计算方法。结合青浦隧道火灾试验数据,运用定位方法对火源点进行预测,并对火源点预测位置与实际位置做出对比,从而对隧道火灾火源点预测提出新方法,为隧道火灾消防设计提供参考。更多还原

【Abstract】 When the tunnel fire broke out,it is significant to locate fire source timely and accurately for evacuation and fire control.In this paper,according to the theory of heat radiation between two heat sources,there is a way to deduce the calculation method of fire source location which is based on the fiber grating temperature sensing system.Combined with the fire test data of Qingpu Tunnel,location method is applied to predict the location of fire source,andthe comparison between the predicted position and the actual is made to check out the availability of theoretical calculation method.This new method is proved to be effective and can provide references for the design of tunnel fire protection.更多还原
