摘要: 为探究多编组地铁列车火灾侧向开口温度特性,构建全尺寸FDS数值模型并利用缩尺寸试验和前人试验数据验证模型准确性。设置不同列车编组和火源功率,考虑车厢内两种典型火源位置(中部/端部),揭示多编组地铁列车侧向开口最高温升出现的位置和规律。结果表明,火源位于列车中心,开口最高温升出现在紧邻火源两侧开口顶部,且随着列车编组增加而下降。火源位于列车端部,受两侧不平衡压力影响,火源向近端侧倾斜,此时最高温升出现于近火源端侧向开口顶部。基于M-Q-H模型构建多编组地铁列车侧向开口最高温升预测模型,可针对火灾预防输出量化数据,为后续建立开口二维温度场模型提供参考。

Abstract: To explore the temperature characteristics of lateral openings during multi-formation subway train fires, a full-scale FDS numerical model was constructed and verified with scaled-down and previous experimental data. Different train formation numbers and fire source powers were set, considering two typical fire source positions (middle part/end). Results show that when the fire source is at the center of train, the maximum temperature rise at the opening occurs at the top of openings on both sides adjacent to the fire source, and it decreases as the number of formation increases. When the fire source is at the train end, affected by the unbalanced pressure on both sides, the fire source tilts towards the proximal side. At this time, the maximum temperature rise appears at the top of the lateral opening near the fire source end. Based on the M-Q-H model, a prediction model for the maximum temperature rise at the lateral openings of multi-marshaled subway trains was constructed. This model can output quantitative data for fire prevention and offer reference for the subsequent establishment of a two-dimensional temperature field model of the openings.
