| 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。

| Abstract: | 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. |
