摘要

爆破挤淤抛石置换断面的结构分层特点及电磁参数差异具备探地雷达检测的基本物理前提。通过浙江洞头某海涂围堤的检测表明，对于底部深度达35 m左右的深厚抛石层，可采用16 MHz低频天线和合适的测试参数探测，查明落底深度、宽度以及腰部宽度等堤身参数，突破探地雷达检测深厚抛石层的局限性。其底部泥石混合层难以识别。

Abstract

The layer characteristics and the difference of electromagnetic properties of the section of the blasting compaction for filling stone have the basic physical testing precondition of ground penetrating radar (GPR). The testing practice of a beach dike in Dongtou of Zhejiang Province

shows that the bottom depth

width

the waist width etc.of the deep thick ripped rock layer

whose bottom depth reaches 35m

can be tested using GPR when the 16MHz lower frequency antenna and the appropriate testing parameters are used. But it is difficult to recognize the mixing layer of soil and stone in the bottom.
