摘要
基于混凝土的失效机理和统计理论 ,用最弱环模型分析了混凝土抗压疲劳寿命分布规律 ,并与正态模型进行了比较 .试验结果表明 ,三参数Weibull分布较正态分布和对数正态分布更适宜描述混凝土抗压疲劳寿命分布规律 .在三参数Weibull分布置信限研究基础上 ,对要求高可靠度。
According to the principle of probability and statistics,the mechanisms of concrete damage and the characteristic of the various distributions are studies,and statistical model of concrete life is established in this paper.On the basis of the academic analyses and test,a statistic model of concrete life,based on the weakest chain theory,is put forward,and three-parameter Weibull distributions to describe its distributing rule is used to consequently study the concrete life.Accordingly,the livability of the life in the specified confidence can be got.
