摘　　要：通过63个100mm×100mm×100mm和63个150mm×150mm×150mm高强混凝土和钢纤维、聚丙烯纤维高强混凝土试件的劈拉试验,探讨了纤维体积率(纤维掺量)及纤维类型对高强混凝土劈拉强度和变形性能的影响,提出了不同类型的钢纤维对高强混凝土劈拉强度的增强系数和劈拉强度的计算公式。Through splitting tensile experiments on 63 plain and fiber （steel and polypropylene fiber） reinforced high-strength concrete speeimens with the dimensions of 100mm × 100mm × 100mm and 63 of 150mm × 150mm × 150mm, the influences of fiber type and volume fraction on the splitting strength anddeformation of high-strength concrete are investigated. The strengthening coefficients of different types of steel fibers on the splitting tensile strength of high-strength concrete are obtained,and a formula for calculating the splitting strength is proposed.
