Anchor rod system based on negative Poisson's ratio structure

The invention provides an anchor rod system based on a negative Poisson's ratio structure, and belongs to the technical field of anchor rods. Two sections of anchor rod structures are arranged in a sectional mode, a negative Poisson's ratio structure layer is arranged on a first anchor rod, an elastic structure is arranged at the position, close to a drilling hole opening, of the anchor rod, and through the arrangement, the length of the anchor rod is increased, and meanwhile the elastic structure is arranged on the first anchor rod; after the surrounding rock deforms, a good anchoring effect can still be achieved, and the elastic structure has good deformation resistance and meanwhile has a good buffering effect. 本发明提供了一种基于负泊松比结构的锚杆系统，属于锚杆技术领域，其通过分段式设置两段锚杆结构，其中，第一锚杆上设置有负泊松比结构层，锚杆靠近钻孔孔口位置设置有弹性结构，通过这样的设置，锚杆的长度得到了加长，同时，在围岩发生变形后，依然可以起到良好的锚固效果，弹性结构具有较好的抗变形能力，同时具有较好的缓冲作用。
