本文从锚杆的力学机制出发,分析了锚杆对围岩的加固作用。指出,岩体抗压强度的提高,是由于锚杆的锚固力改善了围岩的受力工作状态,并据此建立了相应的迭代公式和计算程序框图。
In this paper, starting from the mechanics of the bolt, the reinforcing effect of the bolt on the surrounding rock is analyzed. It is pointed out that the improvement of compressive strength of rock mass is due to the anchoring force of rock bolt improving the stress working condition of surrounding rock and corresponding iterative formula and calculation block diagram are established accordingly.
