摘要
工程物探方法在水文、工程、环境地质工作中得到了广泛的应用,且其应用范围还在不断扩大。与传统地球物理方法相比,探地雷达具有快速便捷、操作简单、抗干扰和场地适应能力强、探测分辨率高等方面的优势。笔者应用探地雷达对广东省东莞市大岭公山边坡的滑坡体进行了勘查,查明了该滑坡体中滑动面的埋藏分布情况;并通过对滑坡体周边岩面的起伏状况进行追踪勘查,结合现场调查成果,对该场地的地质灾害形成机制作出了合理的推断。笔者在此次探地雷达成果获得验证的基础上,对探地雷达资料的分析提出了自己的见解,本文提出的探地雷达资料分析原则可以推广应用到类似的地质勘察工作中。
Engineering geophysical method has been already widely used in the fields of hydrology,engineering,environment etc,and the range of its application is still expanding constantly.Compared with traditional geophysical method,ground-penetrating radar has the characteristics of being speedy and convenient,simple operation,anti-jamming capability,adaptability on site and so on.Based on the exploration via GPR for the landslide slope of Dalinggong Hill,Dongguan City,Guangdong Province,we find out the distribution of slip surface burial of the landslide and keep track of fluctuate conditions of the the rock around the landslide.Combined with field survey results,we make a reasonable conclusion on the formation mechanism of geological disasters.We verify the results obtained based on the analysis of GPR data and put forward our views,and propose that the GPR data analysis principle can be applied to the similar geological survey work.
