| 摘 要： | 利用ANSYS有限元软件，编制开发了锚 以护设计计算机辅助设计系统（ANSYSBOLT），分析了不同地应力条件下合理的锚杆支护结构，提出了在高水平应力条件下，巷道的破坏是扭曲变形破坏，应主要加固顶底板，控制巷道扭曲变形。

| Abstract: | Based on ANSYS finite element software,a computer assistant design system for bolt rock support(ANSYS Bolt)has been developed.By means of ANSYS software,the reasonable structure of bolt support under different site stress has been analysed.It has been found that under high horizontal site stress the distoration is the main reason for roadway breakage.To avoid breakage of roadway,the roof and bottom of roadway must be reinforced to overcome distoration. |
