摘　　要：为了防止城市高架桥爆破拆除时飞石对周围建筑物的影响,进行了桥墩爆破飞石控制实验研究。实验研究了多层性能防护材料的不同排列顺序对飞石的控制效果影响。结果表明采取合理的防护材料和正确的顺序能有效地阻止爆破飞石的危害,减少对周边环境的影响。实验结果可用于城市高架桥爆破拆除时的飞石控制。The experiment of controlling blasting flyrock was carried out in order to reduce the influence of blast flyrock on surrounding building when the urban viaduct was demolished. The effect of multilayer materials arranged in different orders on flyrock protection was studied in the experiment. Results show that the flymck was prevented by using reasonable protective materials and right order, and the harm to the surroundings was decreased greatly, which provides valuable references for controlling llyrock in blasting demolition of urban viaduct.
