摘要
在已知混凝土静压强度分布的基础上使用S N曲线模型推导出一种疲劳寿命满足的分布 ,并对水工混凝土做了大量的等幅抗压疲劳试验 .通过分析发现 ,实验数据能较好地符合该分布 ,同时得出了该种混凝土的S N曲线和P S N曲线 .
Based on the distribution of static compressive strength of concrete, a new distribution of fatigue life was deduced from the equation of S N curve. A lot of the experiments with hydraulic concrete under compressive cyclic loading were conducted. It is shown that the test data approximately follow the present life distribution. The equations of S N and P S N curves of hydraulic concrete are obtained.
