摘要

以地下围岩抗爆工程为背景，以小药量模型试验和数值模拟为手段，通过改变空穴位置、形状、组合形式来考察含空穴的防护层对平面爆炸波、球面爆炸波的衰减屏蔽效果。结果表明，含空穴的防护层可以很好地衰减爆炸波的压力峰值，从而达到保护地下洞室的目的；叉排排列的空穴对爆炸压力峰值的衰减效果明显好于顺排，矩形空穴对爆炸波压力衰减效果优于圆形空穴。研究成果为新型围岩抗爆加固技术提供了一定的参考。

Abstract

Based on anti-explosion engineering of surrounding rock

with the method of little charge model test and numerical simulation

by changing the location

shape

and combination form of cavities

the attenuation and screening effects of defense layer with cavities on planar and spherical blast waves are studied. The results show that defense layer with cavities can weaken peak pressure of blast waves greatly and protect the underground structure. The attenuation effect of staggered cavities on peak value of blast pressure is better than ordered queue cavities obviously; and the attenuation effect of rectangular cavities on blast pressure is better than circular cavities. The results can provide references for new-type anti-explosion technique of surrounding rock.
