Description
Technical field
The present invention relates to the bolt support technology field of the engineering such as underground, ground, especially a kind of test Anchor Agent and rock
The method of interfacial adhesion.
Background technology
Bolt support technology has been widely used for underground, Geotechnical Engineering field, it achieves and is changed by passive protecting
For active support, give full play to country rock self-bearing capacity, country rock is become supporting body from load body, protects to greatest extent
Hold integrality and the stability of country rock.
In the middle of suspension roof support, anchored end anchoring property will directly determine the anchoring effect of suspension roof support, particularly anchor pole,
Anchoring effect between Anchor Agent and country rock.From the point of view of field observation, the principal mode that anchor rod anchored end lost efficacy has: anchor pole
The body of rod is pulled off, Anchor Agent lost efficacy, the body of rod and Anchor Agent bonding failure, Anchor Agent and country rock bonding failure.First three loses
Effect can be improved through process improving and laboratory test research, but for the bonding failure between Anchor Agent and country rock
Mechanism, the most effectively laboratory techniques is studied, and major limitation is in Anchor Agent and rock
The rationally bonding of body and the preparation of experiment test specimen, particularly in further investigation surrounding environment (water, air quality, temperature etc.)
And the impact that rock physical property (Tensile Strength of Rock, surface roughness etc.) is on Anchor Agent Yu country rock interfacial adhesion
Time, not reasonably for the rock-Anchor Agent assembly of experiment.
Summary of the invention
Goal of the invention: it is an object of the present invention to provide a kind of method testing Anchor Agent and rock interface cohesive force, to solve anchor
Gu the problem that agent is difficult with the test of rock interface cohesive force.
To achieve these goals, present invention employs following technical scheme: a kind of test Anchor Agent glues with rock interface
The method of knot power, comprises the following steps:
A) cylinder rock sample is prepared according to International Rock Experiments of Machanics standard；
B) according to cylinder rock sample specification and the Anchorage Parameters of Anchor Agent, design acrylic pipe ring mould and match
The shearing sleeve of set；
C) the acrylic pipe ring shape Mold Making rock-Anchor Agent assembly of design is utilized；
D) being arranged on rock mechanics servo testing machine by the shearing sleeve designed, rock mechanics servo testing machine passes through
The sleeve Anchor Agent surface imposed load to rock-Anchor Agent assembly, carries out shearing experiment；
E) main control computer connection rock mechanics servo testing machine carries out data acquisition, it is thus achieved that bond between Anchor Agent and rock
Power.
Further, described acrylic pipe ring mould internal diameter is more slightly larger than cylinder rock sample external diameter, and acrylic pipe
Ring mould upper inside wall is provided with the cannelure for filling Anchor Agent.
Further, first cylinder rock sample is put into acrylic pipe ring mould, the anchor being then manually stirred
Gu agent is filled to the cannelure on acrylic pipe ring shape mould inner wall top, it is compacted and solidifies i.e. can get rock-Anchor Agent
Assembly.
Further, the cylindrical rock sample Partial Height of described rock-Anchor Agent assembly is 160mm, a diameter of
80mm, the Anchor Agent segment thickness of rock-Anchor Agent assembly is 10mm, height is 25mm；Described shearing sleeve interior
Footpath is 82mm, thickness is 10mm, height is 140mm.
Beneficial effect: the problem that the present invention is directed to Anchor Agent and rock interface cohesive force test difficulty, devising one can enter
The assembly of row Anchor Agent and rock interface cohesive force test, is bonded in Standard rock sample surface by Anchor Agent, and devises and join
Sleeve sheared by set, utilizes rock mechanics servo testing machine to shear rock-Anchor Agent assembly, thus record anchoring
Agent and rock interface cohesive force.On this basis, surrounding environment (water, air quality, temperature etc.) can be furtherd investigate
And the impact that rock physical property (Tensile Strength of Rock, surface roughness etc.) is on Anchor Agent Yu country rock interfacial adhesion,
Anchoring effect offer experiment basis is affected, for optimizing anchor pole for engineering field bolt support technology is analyzed boring wall rock condition
Design of its support provides reference.
