摘要

摘要: 对4种纤维掺量的玄武岩纤维混凝土试件在3种不同应力水平下进行三点弯曲疲劳试验，利用数理统计方法对疲劳试验数据进行了弯曲疲劳寿命的威布尔分布检验，并拟合了不同失效概率下的双对数疲劳方程。结果表明：玄武岩纤维混凝土的弯曲疲劳寿命均符合两参数威布尔分布，且随着应力水平的减小，威布尔形状参数先减少后增大，弯曲疲劳寿命离散性先增大后减小；随着纤维掺量的增加，混凝土的弯曲疲劳寿命分布更加均匀，离散性更小，疲劳寿命大幅度增加。

Abstract: Three-point bending fatigue test was carried out on basalt fiber reinforced concrete specimens with four kinds of fiber contents under three stress levels. Mathematical statistics was used to test the Weibull distribution of the bending fatigue life on the fatigue test data, and fitting the double logarithmic fatigue equation under different failure probabilities. The results showed that the bending fatigue life of basalt fiber reinforced concrete conformed to the two-parameter Weibull distribution, as the stress level decreased, the Weibull shape parameter first decreased and then increased, the dispersion of bending fatigue life first increased and then decreased; with the increase of fiber content, the distribution of bending fatigue life was more uniform, the dispersion was smaller, and the fatigue life was greatly increased.
