摘要
通过对全长锚固锚杆支护机理论证分析 ,借助于塑性区半径、塑性区径向位移等计算式 ,以平衡条件和物理方程为基础 ,推导出锚杆支护参数设计计算公式 ,给出了锚杆长度。
Through theoretical analysis on principle of full length bolt supporting ,using formulas of displacement along radius direction in plastical area and based on balancing condition and physical equation,calculating formula of bolt supporting parameters is deducted.Selecting principle of length diameter,material of bolt and adhesion are also given.
