摘　　要：随着高填方场地强夯地基的大范围推广应用,实现对填方质量高效、快速、大面积的检测,并提供较为准确的岩土力学参数,具有重要的经济及安全意义。基于此,文章结合四川西部某高填方工程实例,阐述了高密度面波法的技术原理和技术流程,并系统开展基于高密度面波法的地基检测研究。通过现场试验、频散分析、反演分析等技术手段,获得高填方地基的剪切波速度分层构造和岩土力学参数,结果表明该方法可高效、直观和大面积地检测填方质量,可为高填方场地质量检测提供相关经验。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 highdensity 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.
