摘要: 针对锚固长度、锚固时间、锚固材料等影响玻璃钢锚杆锚固力的因素,在实验室开展了玻璃钢锚杆拉拔试验研究。通过单因素对比法,分析研究了锚杆锚固长度、锚固时间、锚固材料对锚固力的影响规律,总结出玻璃钢锚杆锚固力随锚固长度和锚固时间的增加而增大,锚固材料的选择应综合各方面因素考虑等规律,对玻璃钢锚杆的支护参数设计及支护机理分析具有一定的指导意义。

Abstract: In view of the factors influencing FRP Bolt anchoring force including anchorage length,anchoring time,anchoring material,FRP Bolt pullout tests are carried out in the laboratory.By contrasting on the single factor,the impacting law of anchorage length,anchorage time,anchorage material on the anchorage force are analyzed.It is concluded that the FRP Bolt anchoring force increases with increasing of anchoring length and anchoring time.Various factors should be fully taken into considerations for selecting the anchoring materials.It plays an important rule in the design of the supporting parameters and the analysis of supporting mechanism of FRP bolt.
