Description
Technical field
The present invention relates to research of the anchor pole in engineering site shock resistance, more particularly to Practical Project consider supporting knot
Anchor pole shock resistance test system and its application process that structure and country rock interact.
Background technology
In recent years, China deep underground engineering construction obtains deep development, while also encountering the ground for becoming increasingly complex
Matter condition.The destructive strong engineering project disaster such as the heavily stressed rock burst for causing and bump is increasingly severe, in this condition
The shock resistance of the anchor pole of lower application is the key of anchoring support effect.
As shown in Figure 1, the generating process of rock burst refers to surrounding rock of chamber under high stress, produces plate cracking first existing
As（Crack is produced）, afterwards with the further accumulation of energy, the phenomenon that part country rock is outwards produced suddenly.In this process
In, anchor pole is highly vulnerable to breakage, and its reason is not only in that rock burst discharges higher energy, forms strong impact, it is often more important that
Stress and strain concentration is caused in anchor pole.
As shown in Figure 2.As anchor surface is coarse and combines closely with Anchor Agent, cause what wall-rock crack opened in rock burst
In the case of, anchor pole near crack is only had the very short body of rod and is separated with Anchor Agent.When rock burst occurs, portion only detached with country rock
Point body of rod can tension elongation, so as to absorb the energy for producing sillar, the part that anchor pole is combined closely with country rock can not then extend
And energy absorption.Therefore, the actual impact resistance of anchor pole only includes the crack institute of deformable segment body of rod tension elongation nearby energy
The energy of absorption.

Some laboratory instrumentations include Chinese patent 201110387388.1,2,012,100,934,515 two kind.Both test devices
All it is that anchor pole one end is fixed, impact load, so actually measured anchor pole impact resistance is directly applied to the other end of anchor pole
Can include that anchor pole whole length tension extends absorbed energy, testing the result for obtaining has larger difference with anchor pole site attribute
Not.The interaction that current experimental provision truly can not reflect between anchor pole-country rock, i.e., the impact load that anchor pole bears with it is existing
Field actual conditions are inconsistent, and can not be reflected directly in reinforcement effect of the Impact Load lower bolt to country rock.
