摘要:
为研究爆炸冲击波在不同曲率弯曲巷道内的传播规律，采用数值模拟手段建立了不同曲率弯曲巷道爆炸模型，分析了爆炸冲击波在巷道内的传播特性及其变化规律, 并结合冲击波超压对人体的伤害程度分类，研究了不同曲率弯曲巷道内爆炸破坏效应分区。模拟结果表明，弯曲角度改变了巷道内冲击波超压分布，随着巷道弯曲角度的不断增大，壁面反射对冲击波超压峰值分布起主要作用，随着传播距离的增加，冲击波超压峰值衰减显著，体现了超压峰值变化的距离效应。此外，巷道弯曲角度的增加整体减小了爆炸损伤严重程度。研究结果可实现对不同曲率弯曲巷道内冲击波超压分布的预测，并为巷道内爆炸事故预防及应急救援提供借鉴。
Abstract:
In order to study the propagation laws of explosive shock wave in bended roadway with different curvature, an explosion model of bended roadway with different curvature was established by means of numerical simulation. The propagation characteristics and variation laws of explosive shock wave in the roadway were analyzed, and the explosion damage effect zoning in bended roadway with different curvature was studied by combining with the damage degree classification of shock wave overpressure on human body. The results showed that the bending angle changes the distribution of shock wave overpressure in roadway. With the increase of the roadway bending angle, the wall reflection plays a major role in the distribution of shock wave overpressure peak. With the increase of the propagation distance, the peak attenuation of the shock wave overpressure is significant, which shows the distance effect of overpressure peak change. Furthermore, the increase of the roadway bending angle reduces the severity of explosion damage on the whole. The results can realize the prediction on distribution of shock wave overpressure in bended roadway with different curvature, and provide reference for the prevention and emergency rescue of the explosion accidents in roadway.
