| 摘 要： | 现行常用的非破损检测结构混凝土抗压强度技术规程中只给出了结构混凝土推定强度的计算方法,其计算结果的可信程度并不能确定.运用概率论知识,引入置信区间的概念,利用非中心t分布建立数学模型,对规程中推定强度进行概率分析,计算其置信度,以供工程实践参考.

| Abstract: | It only provides us with the calculation method of calculation strength of concrete in the present technical specifications for inspection of concrete compressive strength by non-destructive test.The reliability of calculation strength is rarely mentioned in these technical specifications.It introduces confidence interval,and applies noncentral t-distribution.A mathematical model of reliability analysis on calculation strength of concrete is set up by means of the theory of probability in this paper.It calculates the confidence coefficiencet of interval,and provides reference for engineering practice. |
