核子密度仪在南水北调中线渠堤填筑质量检测应用效果分析

The Effect Analysis of the Surface Moisture-Density Gauge applied in South-to-North Water Transfers channel embankment Inspection

针对南水北调京石段工程战线长、工期紧、土方填筑量大、检测频率高等工程特点,阐述了核子——水分密度仪的工作原理,以S41标现场质量检测应用为例,对核子法和环刀法数据进行比较,对采用核子-水分密度仪检测干密度、含水量效果进行分析,提出核子-水分密度仪具有方便、快捷、准确等优点,从而确保了工程质量、提高了检测效率、加快了施工进度,具有良好的经济性和社会效益,值得推广。

Contrapose the characteristic of the middle route project of the South-to-North Water Transfers Project, the paper introduced the theory of the surface moisture-density gauge, And taken the application of the Surface Moisture-Density Gauge in Project S41 compactness inspection as an example, analysed the effect of he nuclear technique and the ring-knife technique in testing the density and moisture, indicate the excellence of surface moisture-density gauge is speedy and exact, So,the construction quality is availably controlled, the construction course is quickened,and surface moisture-density gauge is worth generalizing.
