锚杆支护与围岩共同承载的协调性

锚杆是在围岩体内部发挥支护和加固作用的，如何与围岩的状态和变形特点相协调，是决定锚杆支护效果的关键因素，围岩与锚杆通过锚固力相互作用。通过分解锚固力，研究其作用过程与特点，提出了锚杆与围岩相互作用关系曲线，揭示了影响协调性的主要因素，分析比较了锚杆、注浆和支架支护的承载协调性，得出全长锚固锚杆的承载协调性优于其它支护形式。

Coordination between bolting support and surrounding rock affected by ground pressure

Bolting exert on timbing and reinfore in wall rock, the coordination between bolting support and surrounding rock is the key factor of the bolting effects. Bolts and surrounding rock act on each other by anchoring force, with the analysis of bolting force, and study its process and characteristic, the coordination curves of bolting and surrounding rock is proposed, and the main factors of coordination are presented. On the basis of bearing coordination comparison of bolting, grouting, supporting, the full length anchoring bolts are found to be better in coordination than others.
