摘　　要：为研究装药命中角度对防护结构的爆炸荷载的影响规律,对直墙拱防护结构及围岩进行了系列爆炸试验,得到了直墙拱拱顶、拱脚以及直墙底处的爆炸荷载和位移波形图;通过分析直墙拱不同部位压力峰值和位移峰值发现,随着装药命中角度增大,拱顶处的压力和位移峰值随之而减小,但拱脚处的压力和位移峰值随之而增大,并且拱脚处的位移峰值增大幅度远远高于压力峰值增大幅度,而直墙底几乎不受装药命中角度变化的影响,可供参考使用。In order to investigate the influence of blast loading of protective structure caused by hit angle, a serial blasting test of straight-wall-arch and wall rock was performed to get the waveform of blast loading and displacement at the vault, the foot of arch and the bottom of straight wall; it was discovered that with the increasing of hit angle, the peak blast loading and displacement at the vault decreased and that at the foot of arch increased, and the increasing extent of displacement was more serious than that by blast loading at the foot of arch, but the bottom of straight wall was affected little.
