Application Study on Rayleigh Wave Technology in Coarse Grained Soil Subgrade

Based on review of Rayleigh wave exploration technology and its application in engineering,the development and existing problems of forward and inverse method of dispersion curve of Rayleigh wave are analyzed in this paper.This paper puts forward a thought to establish the relationship between wave velocity and deformation indicator of coarse grained soil subgrade according to the correlation between wave velocity and subgrade strength,where the velocity is measured through theoretical model and test to evaluate the filling condition of coarse grained soil subgrade from a new point and establish the corresponding deformation control indicators.It is the development trend to link subgrade uneven settlement indicator,pavement design indicator and quality evaluation indicator organically in order to improve subgrade construction and pavement design theory to a new level.
