SDG,a non-nuclear soil density gauge,is a nondestructive and high-speed device to test the compaction of the soil-filling density.Based on the understanding of the SDG working principles and needed pre-set parameters,the paper defined the applicability and reliability of SDG rapid testing the compacted soil density by comparing between the conventional sand-filling method and SDG and the indoor simulation tests.The paper focused on the influence of water conditions and compaction situations on the test result,which established a foundation for SDG application in the engineering project.
