全级配混凝土试件拉伸极限应变的统计分析

Statistical Analysis of Limit Tensile Strain of Full Graded Concrete Samples

根据实测资料，给出了全级配混凝土大试件和与其对应湿筛后混凝土小试件拉伸极限应变的概型分布；给出大、小试件拉伸极限应变比值的概型分布和一定置信水平下的置信区间．本文成果为工程应用提供了方便．

On the basis of test data,this paper gives the probability distributions of the limit tensile strain of large full graded samples and small wet screened ones.It also gives the probobility distribution of the ratio of the limit tensile strain of large samples to that of small ones and the confidence interval under a certain confidence level,providing convenience for engineering application.
