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。

Gr ound penetr ating r adar method has the characterist ics of high r eso lutio n and rapid detection speed w hen detecting shallow objects. Based o n the difference o f the dielectric constant betw een t he enro ckment and its adjacent lay ers, the thickness of the rubble enr ockment of sha llow w aters is measured using the gr ound penetrat ing radar method in this paper, and the meas2 urement accur acy of the r esults w as ver ified. The r esult s showed that t he gr ound penet rating radar method can easily identify the to p ripped body and the bottom interface of the enrockment, w hich has high measur ement accuracy.
