摘要/Abstract

摘要： 通过平面装药加载试验，研究了平面装药爆炸荷载作用下不同高跨比结构的抗爆性能。结合历次强爆炸结构效应试验，分析了强爆炸作用下硬岩中支护结构不同破坏等级对应的破坏特征。详细描述了不同高跨比结构的宏观破坏形态，揭示了结构的破坏机制。试验表明：3种不同高跨比结构在荷载环境相同情况下，结构的破坏特征和破坏等级不同，高跨比为1.17的结构试验段，拱部产生挤压、压剪破坏，坑道内呈现中等堵塞，属于严重破坏；高跨比为1.50的结构试验段，拱脚产生贯穿压剪破坏带，直墙受拉伸剥离破坏，坑道内呈现中等剥离，剥落混凝土在底板形成大量堆积，属于中等破坏；高跨比为1.00的结构试验段，主要受劈裂剥离破坏，坑道内呈现轻微剥离，剥落混凝土在底板形成局部堆积，属于中等破坏。综合分析可知，高跨比为1.00的结构型式整体抗爆性能最佳。

Abstract: Through the plane charge loading test, the anti-explosion performance of different height-to-span ratio structures under explosion load of plane charge is studied. Based on the previous structural effect tests of intense explosion, the damage characteristics corresponding to different failure grades of supporting structures in hard rock under the action of intense explosion are analyzed. The macroscopic damage forms of structures with different height-to-span ratios are described in detail and the damage mechanism of structures is revealed. The test results indicate that the damage characteristics and damage grades of three types of structures with different height-to-span ratios vary under the same loading conditions. Firstly, in the structural test section with a height-to-span ratio of 1.17, extrusion and compression-shear damage occur at the arch, and there is a moderate blockage in the tunnel. The structural test section is severely damaged. Secondly, in the structural test section with a height-to-span ratio of 1.50, the arch foot produces a through compression-shear failure zone, and the straight wall is damaged by tensile stripping. The tunnel presents medium stripping, and a large amount of concrete accumulation is formed on the bottom plate. This structural test section is moderately damaged. Lastly, the structural test section with a height-to-span ratio of 1.00 is mainly damaged by splitting and stripping, with slight stripping in the tunnel and a small amount of concrete accumulation on the bottom plate. This structural test section is moderately damaged. The comprehensive analysis shows that the structural type with height-to-span ratio of 1.00 has the best anti-explosion performance.

Key words: plane charge, structural height-to-span ratio, damage grade, damage characteristics, anti-explosion performance
