摘要
介绍了综合管廊电力舱火灾的研究背景和试验条件,通过建立全尺寸综合管廊模型和进行电缆燃烧试验,分析总结了起火方式、环境风速、电缆敷设数量等因素对于温度场分布、CO产生量及产生速率等重要参数的影响规律。
In order to study the characteristics of temperature andflue gas concentration of the electric cabin fire in utility tunnel,a full-scale tunnel model was established to carry out the cable combustion test,and the influencing patterns of igniting mode, ambient wind speed and cable setting up quantity on the distribution of temperature field,CO production volume and rate and other important parameters were analyzed and summarized.
