摘要
Abstract
To examine compaction quality of a subgrade quickly and accurately,a continuous method without breakage to subgrade was used in density test of subgade soil with ground penetrating radar.After different timescompac-tion of the vibratory roller,the electrophysical properties along a length of section were tested with ground pen-etrating radar.A relation was built that between the modulus of relative permittivity of the medium and roller compaction times,the relative permittivity of the soil increased with compaction times.According to the rela-tion of the relative permittivity and roller compaction times,the precise location was signed on radargrams of fixed thickness layer during construction.Based on the relation of reflectivity and density of soil layer with roll-er passes,the reflectivity of soil layers may be determined,so the density of soil layer was gotten.关键词
