| 摘 要： | 弹柔锚杆是在普通锚杆基础上增加弹柔变形体的新型锚杆.通过FLAC对普通锚杆和弹柔锚杆进行对比数值模拟分析,分析结果证实,由于弹柔变形体的应力和形变缓冲效应,使得弹柔锚杆比普通锚杆具有更高的承载能力和更加优异的抗变形性能,特别适用于具有大变形和动荷载要求的支护,值得在锚杆挡土墙工程中进行推广. |
| 关 键 词： | 弹柔锚杆 弹柔变形体 数值模拟 |

| Abstract: | The elastic-flexible anchor is a new type anchor which added a elastic-flexible deformable body on the common anchor.Through developing the comparing numerical simulation analysis between the common anchor and the elastic-flexible anchor by the FLAC,we confirmed that,due to the buffering effect of the stress and deformation in the elastic-flexible deformable body,the elastic-flexible anchor has the higher bearing capacity and more excellent anti-deformation performance,especially applied to the support structure with the requirements of large deformation and dynamic load,and worth popularizing in the anchor retaining wall engineering. |
| Keywords: | elastic-flexible anchor elastic-flexible deformable body numerical simulation |
