| 摘 要： | 将巷道围岩锚固区视为宏观上的各向异性连续介质，由锚杆支护参数确定其等效力学参数，利用快速拉格朗日元法 Ｆ Ｌ Ａ Ｃ 程序，分析了等效模型与实际模型的巷道变形特点。结果表明，等价效果主要依赖于锚杆的支护密度，密度越大，二者越接近；反之，误差增大。此外，锚杆长度对等价效果的影响很小。 |
| 关 键 词： | 锚杆支护 横观各向同性 主动加固 |

| Abstract: | The bolted area of a roadway has been defined as a macroscopic anisotropic continuous medium,and its equivalent mechanical parameters can be gotten from bolting parameters.By using numerical program FLAC(Fast Lagrangian Element Method),The changing characteristics of roadway deformation have been analyzed under the conditions of equivalent model and bolting model.The results prove that equivalent effect depends on bolting density principally,and the higher the bolting density is,the closer they are;otherwise,the error will be enlarged.Moreover,length of bolts has a little influence upon equivalent effect. |
| Keywords: | bolting transverse isotropy active reinforcement |
