摘　　要：以HRB400钢筋作为岩石基础锚筋,通过疲劳性能试验建立HRB400锚筋疲劳寿命与应力水平之间的关系,并通过3参数Weibull分布和Gumbel分布模型进行参数估计,评价了不同失效概率下的HRB400锚筋的疲劳特性,为岩石锚杆基础疲劳性能设计提供了重要的试验参考依据。The HRB400steel bars were used as anchor rods for rock foundations.Through fatigue performance tests,the relationship between the fatigue life of HRB400anchor rods and stress levels was established.Parameter estimation was carried out using the three-parameter Weibull distribution and Gumbel distribution models.The fatigue characteristics of HRB400anchor rods under different failure probabilities were evaluated.This provided important experimental reference for the design of fatigue performance of rock anchor rod foundations.
