ABSTRACT

In this paper, the compaction uniformity of subgrade is studied by single point subgrade com-paction detection index. The subgrade compaction test section of Jingde Expressway and Jingxiong Expressway is selected. PFWD and GeoGauge are used to detect subgrade pressure, and two detection indexes of resilience modulus and Young's modulus are obtained. According to the local statistical principle, the spatial interpolation of different subgrade detection indexes is carried out. Through the comparison of simulation accuracy and cartographic analysis, it is found that the ordinary kriging interpolation has higher accuracy and better visualization effect. By integrating the results of Kriging interpolation with the preliminary exploratory data analysis, it is concluded that the overall compaction uniformity of the subgrade is relatively concentrated, and the uniformity on both sides of the cross section is relatively discrete and the middle is relatively concentrated.
