近年来,越来越多的路基施工工程把核子密度仪使用在路堤填筑的压实质量检测上,配合高效的机械化施工,使施工进度、施工质量都得到了显著的提高。根据洛湛铁路玉林段YQ8标的站场和路基填土施工项目,有针对性地对传统的灌砂法和核子密度仪进行对比试验,以此考核使用核子密度仪在本标段路基填筑质量检测适用性和理论性,为今后的检测工作找出依据。
In recent years, more and more subgrade construction projects have used nuclear densitometry in compaction quality testing of embankment construction, and with highly efficient mechanized construction, the construction schedule and construction quality have been significantly improved. According to the YQ8 superscript Yalu station of Yantai-Zhanjiang Railway Station and the roadbed filling project, the traditional sand filling method and nuclear densitometer are comparatively tested in order to evaluate the quality of subgrade filling using this nuclear densitometer Test applicability and theoretical, to find the basis for future testing.
