Analysis and Mechanism of Impact of GPR Detection Effect Result From Soil Water Content
Using the ground-penetrating radar (GPR) system with the different frequencies and neutron probe, combing with radar image interpretation and the amplitude spectrum, the impact of GPR detection effects on the soil taxonomy and underground pipe were analyzed.The results indicate that when the soil content is 17.02%, the effect on soil taxonomy of 750MHZ antenna is better than 400MHZ, but the effect on underground pipe is same.As soil water content increases to 25.333%, the soil taxonomy of two antennas detection tends to same, and fake stratifications existed.The soil water content accelerates to 36.389%, the detection effect on soil taxonomy and underground pipe is so poor.Attenuation mechanism and propagation characteristics of the high electromagnetic wave were presented to interpret those phenomena.The above analysis shows that the soil water content is one of the main prerequisites for the applications of GPR.Some indicators could be provided to nondestructive test in land consolidation project quality by GPR from this research.
