Exploration on the Application of High-density Surface Wave Method in Foundation Quality Detection
With the widespread promotion and application of dynamic compaction foundation in high fill site,it is of great economic and safety significance to realize the efficient,rapid and large-area detection of fill quality and provide accurate geotechnical parameters.Based on this,combined with a high fill project in western Sichuan,this paper expounds the technical principle and technical process of high-density surface wave method,and systematically conducts research on foundation detection based on high-density surface wave method.Through field test,frequency dispersion analysis,back analysis and other technical means,the shear wave velocity layered structure and geotechnical mechanical parameters of high fill foundation are obtained.The results show that this method can detect the fill quality efficiently,intuitively and extensively,which can provide relevant experience for the quality detection of high fill site.
