结合目前最先进的数字钻孔成像与钻孔地质雷达技术,开展了以高速交通工程线路经过区域地质为对象的动态勘察技术研究,提出了基于钻孔雷达和数字摄像的动态勘察方法,并给出了动态勘察技术的定义、操作流程.通过对钻孔雷达数据与数字摄像数据的对比分析,发现两者的解译结果有许多相关性,可互为补充,钻孔图像中的结构特征与雷达图像中目标特征能够建立起直观的对应关系,为目标体解译创造了条件.并通过工程实践证明,基于钻孔雷达与数字摄像的动态勘察技术能较好地反映测试地区岩土体的形态特征,是一种新的、有效的工程地质勘察方法.%In this paper, a new integrated method for dynamic geological survey based on a ground-penetrating radar ( GPR) and digital imaging is put forward with the purpose of the geological examination for large construction engineerings , and its definition, operational flow are given. Through comparison of the borehole digital images and the GPR data, it is found that their interpretation results are coherent and complementary, and it can obviously help to interpret the geological objectives in construction sites by determination of the corresponding characteristics of reflected information of these two tools. Finally, a case study proves that the dynamic exploration survey based on the GPR and digital borehole imaging is available and practical.
