【摘要】 柔性注压锚杆是一种结构和锚固机理新颖的全长锚固锚杆,已有的研究缺少其受力、锚固力与锚固机理的分析。通过柔性注压锚杆地面和井下试验,对其锚固力、锚固机理进行了理论和试验分析,导出其承载能力的计算与分析方法,为其设计、试验和应用提供了一定的理论依据。研究和试验结果表明该锚杆对多种围岩(煤、岩、碎石等)有良好的锚固能力和适应性,现场应用方便。更多还原

【Abstract】 The bolt is a new kind of structural bolt.Few researches have been carried out on its force,deformation and action mechanism at present.Based on the experiment on the bolt,the theoretical analysis on anchoring ability and the action mechanism are given,the anchoring forces are defined and the analyzing method of anchoring force is presented.The mechanical model for anchoring mechanism is established and used for the theoretical solution of bolt parameters.The analysis gives some help for the structure designt,est and appliance to the bolt.The analysis and test results show that the bolt with its good anchoring ability is suitable for some surroundings,such as coal,rock,detritus and it is simple and convenient for application in engineering.更多还原
