Three-section type group anchor anchoring system
The invention discloses the technical field of anchoring systems, and particularly relates to a three-section type group anchor anchoring system which comprises an anchoring mechanism, an anchoring sleeve and reinforcing ribs, and the anchoring sleeve is sequentially divided into an inner cone section, an arc section and a straight barrel section; the bonding medium is a segmented variable stiffness load transfer medium; the inner cone section is used for increasing the radial extrusion stress of the bonding medium and the reinforcing rib, and effective anchoring of the reinforcing rib can be enhanced; compared with a traditional inner conical anchoring system with the maximum radial stress at the loading end, the radial stress distribution rules of the novel anchoring system are just opposite, namely, the radial stress at the loading end is minimum, and the phenomenon of stress concentration at the loading end is effectively avoided. By means of the structure, the longitudinal shear stress and the transverse shear stress of the reinforcing ribs close to the loading end are greatly reduced correspondingly, and the bending and pulling combined stress degree of the reinforcing ribs is reduced.
本发明公开了锚固体系的技术领域,尤其涉及一种三段式群锚锚固体系,包括锚固机构,包括锚固套筒和加固筋,所述锚固套筒依次分为内锥段、圆弧段和直筒段;粘结介质,所述粘结介质为分段变刚度荷载传递介质;所述内锥段用于增大粘结介质与加固筋的径向挤压应力,能够增强对加固筋的有效锚固;相比于传统的内锥形锚固体系加载端径向应力最大,新型锚固体系的径向应力分布规律刚好相反,即加载端处的径向应力最小,有效避免了加载端应力集中的现象。此构造也使得加载端附近加固筋的纵向剪应力及横向剪应力也相应大幅减小,降低了加固筋的弯拉组合受力程度。
