| 在完成掺有粉煤灰、粉煤灰和磨细矿渣、粉煤灰和聚丙烯纤维3类高性能混凝土轴心抗压静载强度试验基础上，分析了高性能混凝土抗压静载强度的概率分布模型．基于文献研究成果，推导出了高性能混凝土疲劳寿命概率分布和疲劳强度表达式．最后，通过研究不同掺和料对高性能混凝土轴心抗压静载强度均值和方差的影响，利用疲劳强度计算公式，对比分析了不同掺和料高性能混凝土在高、低应力比之下的疲劳强度变化规律． |

| Abstract: |
| High performance concretes mixed with fly ash,fly ash and blast furnace slag,and fly ash and polypropylene fiber were designed and cast respectively.Based on the test results,the probability distribution for the static axial compressive strength of high performance concrete(HPC)was studied and the probability distribution of fatigue life and the expression of compressive fatigue strength were proposed.Finally,the comparative analysis for fatigue strength of HPC under both high and low stress ratio were made. |
| Key words: high performance concrete(HPC),compressive strength,fatigue strength |
