根据锚固构件与围岩的相互作用机理,为了提高巷道锚固岩体的整体刚度,从分析刚度控制对锚固岩体的作用和影响入手,找出影响锚固岩体刚度的主要影响因素,提出以高强度、高预紧力和高锚固力为基础,以锚杆(索)群连锁锚固为核心技术的锚固岩体刚度控制技术,并结合现场试验对其合理性进行分析.研究表明,巷道锚固岩体刚度控制设计合理,能够减少巷道围岩的有害变形,有效控制其稳定性,满足安全经济高效的生产目标要求.
According to the interaction mechanism between anchoring members and surrounding rock, in order to improve the overall stiffness of anchored rock mass, the paper analyzes the main factors affecting the rigidity of anchored rock mass from the analysis of the effect and influence of stiffness control on anchoring rock mass, Strength, high pre-tightening force and high anchorage force, and the anchorage rock mass stiffness control technology based on anchor bolt (cable) group anchoring as the core technology, and combined with field test to analyze its rationality.The study shows that the anchorage rock Body stiffness control design is reasonable, can reduce the harmful deformation of roadway surrounding rock, effectively control its stability, to meet the safe and economical production targets.
