摘要
详述了国内外锚杆锚固力的试验研究成果,包括:拉拔载荷下锚杆粘锚力的分布规律以及锚杆形状、锚固剂强度和岩体强度对粘锚力的影响;岩体特征、锚固单元特征和加载特征对加锚节理面抗剪性能的影响;锚杆长度、锚杆预紧力、树脂环体厚度及淋水、动载荷等其他因素对锚固效果的影响。讨论了锚杆锚固力试验研究中存在的问题及需进一步研究的方向。
This paper introduced clearly test results of anchoring force for anchored bolt at home and abroad, including distribution role of anchoring force under tensile loading and influence of anchored bolt shape, strength of anchoring agent and rock strength on anchoring force, influence of rock mass characteristics, anchoring cell characteristics and loading characteristics on anti-shearing of joint anchored and influence of bolt length, pre-tightening force, thickness of resin ring body, trickling and dynamic loading on anchoring effect. It also discussed problems in anchoring force test for anchored bolt and research tendency.
