摘要
分析了钢纤喷射维混凝土和挂网喷射混凝土的巷道支护机理，提出两种支护方法的力学模型，并对其抗拉能力进行了计算与比较，证明了钢纤维砼替代挂网砼的可行性。
Tunnel supporting mechanisms of steel - fiber spray concreter and the mesh spray concreter are analyzed. Two mechanical models of them are put forward. The tensile strengths of the two models are calculated and compared. And the feasibility of steel- fiber spray concreter superseding the mesh spray concreter is proved.
