隧道电缆的火灾影响因素与仿真分析

Influencing Factors and Simulation Analysis of a Fire Risk in Power Cable Tunnel

随着隧道电缆的增加,地下隧道为人们带来便利的同时还带来了火灾风险。本文在分析电缆火灾致因的基础上,结合流体力学模型和燃烧模型计算原理,通过仿真分析了电缆在不同工况下燃烧后的温度和燃烧速率变化曲线。结果表明,合理的铺设方式可以降低火灾温度和燃烧率。本研究为我国电力电缆隧道的防火工作提供了参考和借鉴。

In view of the increase of power cable tunnel, underground cable tunnel brings convenience to people and fire hazard. In this paper, based on the analysis of the causes of cable fire, combined with the hydrodynamics model and combustion model calculation principle, the temperature and combustion rate curves of the cable after combustion under different conditions are analyzed by simulation. The results show that the reasonable laying way can reduce the fire temperature and combustion rate. This study provides a reference for the fire prevention of power cable tunnels in China.
