摘　　要：分析了聚丙烯纤维掺量、配箍率、混凝土强度等级、剪跨比四个参数对混凝土梁斜截面初裂剪力和抗剪承载力的影响。提出了聚丙烯纤维混凝土梁斜截面受剪承载力计算方法,为工程实践提供理论依据。Through analyzing the main variables were polypropylene fiber volume fraction,stirrup content,concrete strength and shear span ratio.Studying that the diagonal cracking strength and shear strength of reinforced concrete beams were impacted on parameter of the four.Based on the results and analysis,the calculation method of the shear capacity of polypropylene fiber reinforced concrete beam is proposed,which can provide the theoretical basis for the engineering practice.

关 键 词：聚丙烯纤维 初裂剪力 抗剪承载力 剪跨比
