土遗址夯筑支顶加固表面色度检测的影响因素研究
Influencing factors of chromaticity detection on the reinforced surface of rammed support roof for soil sites
摘要
Abstract
The assessment of appearance and coordination for earthen archaeological site reinforcements,which is traditionally done by visual inspection,is greatly influenced by the observer's subjectivity.Quantitative evaluation has become a critical issue for assessing the effectiveness of these reinforcements,in which chromaticity is a key metric.To improve the accuracy and scientific validity of chromaticity measurements on the surface of the compacted supports,tests on soil samples with varying color proportions were conducted.It was determined that the human discernible chromaticity difference ΔE is ranged from 3.62 to 4.08.A chromaticity difference threshold of ΔE=4 is proposed as the critical value for quality control of the color difference in the compacted supports of earthen archaeological sites.Field tests revealed that factors such as ambient light,edge light leakage,and uneven testing points can affect the results,while the impacts of lighting conditions and edge light leakage are minimal.The significant deviations in chromaticity measurements are occurred when the testing location has a depression deeper than 5 mm and larger than 50 mm2.Based on these findings,this study introduces specific conditions for chromaticity testing in compacted earthen archaeological sites,which can offer theoretical and technical support for the standardized preservation of such sites.关键词
