Abstract

The invention provides a detection method of a cooperative effect generated in anchoring body under an anchor pole cooperative reaction, belonging to a detection method of a cooperative effect generated under a cooperative reaction. The detection method comprises a step of selecting a model test piece material, making a model test piece, and determining the detection method of an anchoring body cooperative reaction under a pre-tightening force anchor pole effect through the model test piece, a step of detecting the shape, range and evolution rule of the anchoring body, a step of determining detection data, a step of establishing a corresponding relation between the cooperative reaction and tunnel surrounding rocks stability control through cooperative effect calculating, obtaining and evaluating the anchoring body cooperative effect, realizing a condition that the macroscopic function of a cooperative anchoring system is larger than the linear superpose sum of each sub system, and improving the stress state of a tunnel surrounding rocks anchoring structure. The detection method has the advantages that the bearing ability of the tunnel surrounding rocks anchoring structure can be substantially improved, the distribution shape, range and development evolution rule of the anchoring body cooperative effect are obtained, and the anchoring body intensity, rigidity, bearing ability, and anti-deformation ability are improved.

Description

technical field [0001] The invention relates to a detection method for the synergistic effect produced by the synergistic action, in particular to a detection method for the synergistic effect produced in the anchor body under the synergistic action of the anchor rod. Background technique [0002] Roadway surrounding rock anchoring is a collective behavior of bolts (cables), surrounding rock, bonding materials, and composite components. This behavior has obvious self-organization characteristics and conforms to the general evolution law of nonlinear systems. Synergistics is a scientific theory, advanced method and effective tool to describe the behavior characteristics and evolution law. [0003] At present, there are traditional support methods such as joint support and composite support, and there is objectively "synergy" in traditional support methods such as joint support and composite support, but there is no systematic way to effectively improve the roadway surrounding...
