探地雷达技术在探测边坡破碎带中的应用

Application Research of GPR in Detecting Fracture Zone of Border Slope

探地雷达是利用高频电磁脉冲的反射对地下目的体及地质现象进行探测的一种高效浅层勘探方法,随着电子技术和计算机技术的不断发展,该技术的应用领域不断扩大。本文从探地雷达的基本原理出发,结合在浙江省金丽温高速公路某段边坡探测的应用实例,详细分析了破碎带的雷达图像特征。通过理论与实践的相互结合,证实利用探地雷达进行边坡破碎带探测是科学可行的,拓宽了该技术在岩土工程勘察中的应用,进一步表明该技术具有较强的推广潜力。

Ground penetrating radar is an effective shallow exploration method which use the reflection of high frequency electromagnetism pulse wave to detect the object and geologic phenomena under ground. With the development of electron and computer technique, the application domain of this method is keeping enlarge. Based on the working principle of GPR and compbine with the application case in Zhe Jiang province, this paper analyzed the GPR image character of border slope. A conclusion is obtained that the ground penetrating radar is a scientific method to probe fracture zone via theory and practice. Moreover, the apply field of this method is developed in civil engineering.
