| 摘 要： | 首先讨论了探地雷达理论中的探测深度和分辨率等重要概念,然后以某海岛爆破挤淤抛石置换筑堤工程为例,详细分析了抛石、淤泥等介质层的电性差异及雷达波形特征,并将解释结果与钻探资料对比分析了雷达检测的效果.检测表明,低频天线可用于检测深厚抛石层,取得深达35 m左右抛石层底部反射波信息,但无法分辨出底部泥石混合层.雷达反射波形易受地面平整程度、抛石层孔隙度、含水量及含泥(砂)量等因素的影响. |
| 关 键 词： | 海堤 爆破挤淤 抛石 检测 雷达 探测深度 分辨率 |

| Abstract: | This paper discusses some important concepts,such as exploration depth and resolution of ground penetration radar(DPR),and then analyzes in detail the electric property difference and ground penetrating radar(DPR) image characters of riprap,silt and some other medium as well as the detecting effect of GPR through the comparison between interpretation re-sults and boreholing data,based on a case study of riprap replacing embankment project by blasting-extruding silt on an is-land.Using the lower frequency an... |
