摘要

为合理地表征测量值的分散性,确定测量结果的有效性,检验检测机构应制定和实施测量不确定度评定程序,以确保在需要时能够进行准确的评定.在评定测量不确定度时,应充分考虑影响不确定度的因素,建立相应的数学模型,精确计算每个因素引起的不确定度分量,然后综合计算出合成标准不确定度和扩展不确定度,给出最终的结果表示.以建筑工程检测中常用到的混凝土碳化深度检测及基桩缺陷深度检测为例,对测量不确定度的评定方法进行了实际应用,得到了比较准确的测量结果.

Abstract

To reasonably characterize the dispersion of measurement values and determine the validity of measurement results,inspection and testing institutions should develop and implement measurement uncertainty assessment procedures to ensure accurate assessment when needed.When evaluating measurement uncertainty,factors that affect uncertainty should be fully considered,corresponding mathematical models should be established,and the uncertainty components caused by each factor should be accurately calculated.Then,the composite standard uncertainty and extended uncertainty should be comprehensively calculated,and the final result should be provided.Finally,taking the commonly used concrete carbonation depth detection and foundation pile defect depth detection in construction engineering inspection as examples,the evaluation method of measurement uncertainty is practically applied,and relatively accurate measurement results are obtained.
