| 摘 要： | 现行规范中计算标准值时所采用的统计修正系数是按统计学中置信度为95%时进行修正的,但同时规范规定其置信度不小于90%时所得统计修正系数能够满足工程勘察设计精度的要求。因此,将置信度减少为90%来计算统计修正系数,并进行了实例分析,验证了统计修正系数的可靠性。

| Abstract: | The existing norms to calculate the standard values used in the statistical correction factor is based on statistical confidence level of 95% when to correct,but at the same specification of their level of confidence not less than 90% of the proceeds statistical correction factor to meet the engineering survey and design accuracy.Therefore,this article will be reduced to 90% confidence level to calculate the statistical correction factor,and conducted case study to verify the reliability of the statistical ... |
