Abstract
A test system and test method continuously and intelligently measures water content of subgrade in real time. The test system is based on the theory of resistivity, and is equipped with a wheeled machine to measure the water content of subgrade. The wheeled machine includes scroll roller. The test system includes: at least one set of electrode including four probes wherein detection parts of the four probes are linearly and equidistantly arranged on the scroll roller. The arrangement direction of the detection parts of the four probes is parallel to the axis of the scroll roller; a data integration apparatus is connected to the four probes and used for performing data calculation, analysis, and transmission; the electric source is connected to data integration apparatus and used for supplying a working current. The system and method can realize automatic signal collection, non-destructive detection of subgrade soil and dynamic water content measurement.
