Abstract:
Physical experiment is a commonly used research method in the field of modern natural science, but the experimental method in a single study is often limited, which cannot fully reflect the whole picture of the problem to be studied. In order to enrich the methodological content in this field, drawing on the ideas of reductionism and systems science, a combination of purpose sampling and subject snowball sampling was used to obtain the analyzed sample literature, and a comprehensive review of the physical experimental research methods of mine bolt was made. In terms of single components, the experimental methods of bolt body, anchoring agent, pallet and metal mesh were summarized and analyzed. In terms of anchoring system, the tensile, shear and similar simulation experiments were summarized and analyzed, and the problems of similar simulation in terms of similar materials, similar structures, similar unstable non-continuous fields, similar processes, similar boundary conditions and similar systems were pointed out. On-site anchorage system experiments can be divided into detective experiments, monitoring experiments, research experiments and other types. In the current physical experimental research on bolt, the experimental objects include component elements, local anchoring systems, anchoring engineering, etc., almost most of the research topics can be classified as performance research, mechanics, materials science experimental methods are used relatively frequent, force, length, time is the basic unit for experimental evaluation. For future research, the existing research can be further enriched by comprehensively applying multidisciplinary research methods, increasing attention to on-site anchored solids, and drawing on system science concepts.
