| Abstract: | First,a theory of the measurement of soil water content by FDR(Frequency Domain Reflectometry)is introduced.Second,a calibration experiment processes of the measurement of soil volumetric water content are described in detail.This calibration experiment is based on loess samples collected in Xi'an at compactness of 95%,and the calibration curves of the FDR is achieved.Last,the application of site monitoring in an indoor roadbase model is introduced.Analysis result indicates that the absolute deviation betwe... |
