摘要
为了合理表征在超声回弹综合法检测混凝土抗压强度过程中检测结果的分散性,对测量结果的不确定度进行了分析。通过相关的数学模型确定不确定度的来源,并对各不确定度来源进行独立分析,最终确定了各来源的不确定度分量值及其最终测量结果的灵敏系数。
In order to express the discreteness of the test result for compressive strength of concrete with ultrasonic-rebound combined method, the uncertainty of its result is needed to be analyzed. The source of uncertainty according to relevant mathematical models is determined. Then, some independent analysis should be done about the uncertainty source, so as to confirm the sources of uncertainty values and the sensitivity coefficient about its final measurement results.
