地下洞室锚固抗爆技术研究之现状

Current research state and of anchor explosion-resisting technique for underground cavern

锚固抗爆技术是提高地下洞室抗爆性能的重要技术手段。综述了国内外地下洞室锚固抗爆技术的研究现状,包括全长粘结锚杆抗爆技术、预应力锚索抗爆技术、锚索+锚杆复合抗爆技术、屈服锚杆抗爆技术及端部消波锚杆抗爆技术;在此基础上,分析了锚固抗爆技术研究中存在的问题,指出了今后应重点开展的研究工作。

Anchor explosion-resisting technique is an important technique measure for improving the explosion-resistance of underground cavern. In this paper, the current research state of internal and foreign anchor explosion-resisting techniques arc summarized, including fully bonded bolt explosion-resisting technique, pre-stressed cable bolt explosion-resisting technique, bolt ＆ cable bolt explosion- resisting technique, yielding bolt explosion-resisting technique and end wave absorbing bolt explosion-resisting technique. Based on the summarization, the existing problem in the research of anchor explosion-resisting technique is analyzed, and the research work which should be carried out in future is pointed out.
