土坝及土堤干密度检测控制技术

Check Measurement and Control Technique of Dry Density of Earth Dam and Earth Levee

使用进口或国产核子密度仪测定土坝及土堤压实干密度具有操作简便、快速之优点。通过对不同的土质进行了现场核子密度仪与环刀法测定干密度的对比试验后 ,证明核子密度仪在测定土的干密度时 。

Determination of compacted dry density of earth dam and earth levee by import or domestic nuclear densimeter has the advantages of simple and speedy operation. But after the field check experiments for determination of dry density with different soil qualities by nuclear densimeter and cutting ring, it is proved that verifying by the cutting ring method is necessary and important as detecting the dry density of soil by nuclear densimeter.
