摘　　要：为探明路基路面野外观测站土壤水分传感器的有效标定方法,以准确监测不同环境条件下公路路基路面各结构层含水率的量值及变化规律,采用标准土样法对拟用于三江至柳州高速公路路基路面野外观测站的土壤水分传感器进行了标定,并以观测站钻孔施工挖出的路基土样为比对土样,将传感器法与烘干法的测量结果进行了比对分析,验证了标准土样法标定土壤水分传感器的有效性与适用性,对制定合理有效的公路工程专用土壤水分传感器校准规范具有重要的参考意义。结果表明:标准土样法是有效的路基路面野外观测站土壤水分传感器标定方法。In order to explore the effective calibration method of the soil moisture sensor of the subgrade and pavement field observation station,and to accurately monitor the quantity value and change law of the moisture content of each structural layer of the highway subgrade and pavement under different environmental conditions,this paper uses the standard soil sample method to calibrate the soil moisture sensor proposed to be used in the subgrade and pavement field observation station of Sanjiang Liuzhou expressway,and takes the subgrade soil sample excavated from the borehole construction of the observation station as the comparison soil sample,the measurement results of the sensor method and the drying method are compared and analyzed,which verifies the effectiveness and applicability of the standard soil sample method for calibrating the soil moisture sensor,and has important reference significance for formulating a reasonable and effective calibration specification of soil moisture sensor for highway engineering.The results show that the standard soil sample method is an effective calibration method for soil moisture sensor of subgrade and pavement field observation station.
