本文提出了我国湖南省五座中小型土坝(坝高约20公尺)以及一座大型土坝(坝高48公尺)心墙粘性土料所具有的稠度指标数值,并与我国常用室内击突试验所得出击实土料的稠度指标数值作出比较。文中也讨论了压实土料的饱和度和含气率的确定方法。这些数值的选用,有助于一般干筑填方压实粘性土料质量控制的确定。
This paper presents the consistency index values of five medium and small earth dams (dam height about 20 meters) and a large earth dam (48 meters high) core wall clay material in Hunan Province of China, and it is also used with common indoor blows in China. The consistency index values of compacted soil material obtained from the sudden test are compared. The method for determining the saturation and gas content of compacted soil is also discussed. The selection of these values is helpful for the determination of the quality control of general dry-filled compacted clay materials.
