Scope
This document specifies the general requirements for the detection of soil density and moisture content using the complex impedance method, the detection instruments, the modeling of standard soil models, and on-site detection. This document is applicable to the detection of the density and moisture content of earthworks in water conservancy projects such as embankments, earth-rock dams, and foundation treatment using a nuclear density gauge based on the complex impedance method. The soil types tested include fine-grained soils with a gravel content of no more than 25% and a maximum particle size of no more than 15 mm.
