探地雷达法在探测浅层目标体时具有分辨率高、检测速度快等特点。文中基于抛石体与其相邻层之间介电常数的差异,应用探地雷达法测量了浅水域薄层抛石体的厚度,并对测量成果进行了精度验证。结果表明探地雷达法能较容易划分出抛石体的顶、底界面,测量精度较高。

Ground penetrating radar method has the characterist ics of high resolution and rapid detection speed w hen detecting shallow objects. Based on the difference of the dielectric constant betw een t he enrockment and its adjacent layers, the thickness of the rubble enrockment of shallow w aters is measured using the ground penetrat ing radar method in this paper, and the meas-urement accuracy of the results w as verified. The result s showed that t he ground penet rating radar method can easily identify the top ripped body and the bottom interface of the enrockment, w hich has high measurement accuracy.
