Abstract ：
为研究半横向通风下隧道内发生火灾时,顶棚有效高度对顶棚烟气温度分布的影响,建立1∶10的缩尺寸隧道模型进行试验.在半横向通风方式下,通过改变通风风速、油池尺寸和顶棚有效高度等参数,分析燃料顶棚烟气最高温升的变化规律和顶棚烟气温度的纵向分布特征.结果表明,随着顶棚有效高度的增加,顶棚最高温升逐渐降低,而且隧道顶棚烟气温度纵向衰减更加显著;同时,风速的增加导致顶棚最高温升大幅下降,相较于纵向通风,半横向通风下顶棚最高温升明显偏小,顶棚烟气温度纵向衰减更明显.据此提出新的考虑通风风速、顶棚有效高度和火源功率的无量纲最高顶棚温升和顶棚烟气温度纵向衰减的经验模型.

Abstract ：
The maximum ceiling temperature and transverse temperature distribution under the condition of transverse double fire sources are experimentally and theoretically studied. A series of experiments were carried out in a scaling tunnel (1:20) to investigate the effects of heat release rates (HRR) and distance of the two fire sources (S) on the maximum temperature and the transverse temperature distribution beneath tunnel ceiling. Results shown that when the fire sources were set close to each side of the wall, the location of the maximum temperature was found at the middle ceiling of the tunnel. A inverted "N" shape ceiling temperature distribution, with the ceiling temperature firstly decreased and increased and then decreased, was found along the half-cross section of the tunnel. New maximum and transverse ceiling temperature models were developed with considering the distance and heat release rate of the two fire sources, and considering the air entrainment restrictions by the sidewall. New findings of this work can provide a significant reference for the risk assessment of tunnel fires with two transverse fire sources.

Abstract ：
A new N-P-Cu containing supermolecular assembly network (MPCSN) was fabricated with titanium carbide (Ti3C2Tx) nanosheets through intermolecular forces, and then, the flame-retardant thermoplastic polyurethane (TPU) nanocomposites were synthesized by melt blending. The obtained results of the TPU/Ti3C2Tx-MPCSN system indicated that the temperature corresponding to T-5% of TPU nanocomposites by adding 2% Ti3C2Tx or 2% MPCSN decreased to 269.1 and 311.5 & DEG;C, respectively. Simultaneously, a well dispersion of the loading of 1.0 mass% Ti3C2Tx-MPCSN was found in TPU matrix. Accordingly, the thermal stability of TPU can be found to be substantially improved in the thermogravimetric analysis, which was embodied in the mass loss of TPU/Ti3C2Tx-MPCSN-1.0 reached up to 8.47 mass%. Moreover, the cone calorimeter tests revealed that the peak of heat release rate, the total heat release, carbon monoxide production rate and total carbon monoxide yield of the TPU nanocomposite were prominently diminished by 16.1%, 37.5%, 18.8% and 37.6%, respectively. This provides clues to the flame-retardant mechanism of TPU nanocomposites: The modified Ti3C2Tx is combined with MPCSN through a cross-linked network grown on the surface of the carbon layer, which not only prevents the leakage of combustible gas, but also catalyzes the formation of the carbon layer. This work demonstrates a novel design for improved Ti3C2Tx with supramolecularly assembled networks to reduce potential fire risk in practical TPU applications, applying to applications in polymer materials.

Abstract ：
Safety concerns on cable tray fires in urban utility tunnels, which may further trigger huge casualties, ceiling structure damages, power failures and other domino effects, attract increasing attention in recent years. Determining the maximum excess ceiling gas temperature (MECT) induced by cable tray fires in urban utility tunnels is crucial to evaluate the fire risks. A series of one-layer horizontal cable tray fire experiments to explore the MECT were carried out in a large-scale utility tunnel without mechanical ventilations. The number of cables on the tray was varied from 8 to 18 in the experiments. The experimental results showed that the cable tray fire burning could be divided into three distinct stages, including ignition, self-sustaining and decaying stages. In the self-sustaining combustion stage, the cable tray was found to burn relatively steady. The mean MECT was also investigated since it represents one of the main characteristics of the cable tray fire. By redefining two parameters (the heat release rate and the effective ceiling height) in three classical MECT models proposed originally based on pool-fire, these three models could be extended to be able to predict the mean MECT generated from the cable tray fire (solid combustible) within 20% deviations. Consequently, two novel models were respectively proposed to predict the mean MECT at the self-sustaining burning period and the instantaneous MECT of one-layer horizontal cable tray fire in utility tunnel, which would be useful in the field of fire protection engineering.
