传统的锚杆作用机理大多从锚杆自身的受力状态入手，对于锚杆整体结构与围岩之间相互作用的规律研究较少。通过理论分析、现场实测等手段，从全长锚固预应力树脂锚杆加固围岩的轴向锚固作用、托锚力作用和横向锚固作用来着重分析锚杆、托盘、锚固剂与围岩之间相互作用的规律，以及与围岩长期相互作用过程中锚杆的受力分布特征，并通过现场支护试验校验了全长锚固预应力树脂锚杆的锚固效果。研究所得结论可为全长锚固预应力树脂锚杆的支护设计和现场支护应用提供理论参考。

Traditional anchoring mechanism is mostly concerned on the stress state of rock bolt itself, while the laws of interaction between overall rock bolt structure and surrounding rocks are rarely studied.In this paper the means of theoretical analysis and filed test are used to analyze the interaction mechanics among the bolt,tray,anchoring agent from the perspectives of the axial anchoring effect,supporting anchoring effect and lateral anchoring effect of the fully anchored pre-stressed resin bolt,and the stress distribution of bolts during its long-term interaction is analyzed as well. In-situ supporting tests verified the anchoring effect of the fully anchored pre-stressed resin bolt.The conclusion pro-vides theoretical reference for the supporting design and in-situ application of supporting.
