摘要
为了验证钢纤维混凝土代替素喷的可行性,从理论、支护效果和经济方面对2种支护方式进行对比分析。在理论上,分析钢纤维混凝土的增强机理,对比二者的力学性能,分析其对动荷载的适应性;在支护效果上,对2种支护方式进行现场工业试验,进行支护效果现场调查及巷道变形监测;在经济上,全面分析巷道掘进、支护过程中的经济因素,进行经济评价。结果显示:钢纤维砼在巷道支护中代替素喷在理论上可行、经济上合理、安全上可靠。
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.
