Abstract

In order to verify the feasibility of steel-fiber concrete superseding plain concrete in roadway support, the comparative analyses between these two kinds of support methods are performed from aspects of support theory,support effect and economic benefits.In theory,by analyzing strengthening mechanism of steel-fiber concrete and comparing the mechanical properties of them,this paper aims to analyze steel-fiber concrete’s adaptability to dynamic load.In support effect,field tests of the two support methods are conducted,aiming to investigate support effect in field and detect the roadway deformation.Economically,the economic factors in the process of drifting and supporting are analyzed comprehensively for the sake of economic evaluation.In conclusion,the research results show that the idea of steel-fiber concrete taking the place of plain concrete in roadway support is feasible in theory,reasonable in economy and reliable in safety.
