摘要
基于最大标准差法和最大变异系数法,在混凝土试验中能充分利用以往数据和经验提 供的信息,在相同试件个数情况下,与单侧容限系数法相比可得到更接近母体百分位值下限的 许用强度和安全寿命。
According to the methods of maximum standard deviation and maximum variation coefficient, the information from former data and experience in the concrete test study can be taken a dvantage of. The one -sided lower confidence limits of the population percentiles by the methods are greater than those by the one -tolerance factor at given confidence level, the number of specimens required fewer.
