摘要
该文在简述地质雷达工作原理的基础上,对地质雷达超前预报的探测方法、参数选取、测线布置、图像解释等进行介绍,并建立了拟探测区域完整岩体、破碎带、富水带以及岩溶洞穴等典型地质目标体的地质雷达图像,在对其图谱特征的分析研究的前提下,结合具体的工程实例,说明地质雷达在公路隧道短期地质预报中的实用性和有效性。
In this paper, based on the work principle of ground penetrating radar, the detection method, the parameters selection, line layout, images interpretation and so on of advance geological forecast of GPR are intro- duced, moreover, the typical radar images of intact rock mass, fracture zone, water enriched zone, the karst caves and other geological targets are established in the planning detected region. On the premise of analyzing the characteristics of radar mapping, and combining with specific examples, the practicality and efficiency of GPR in short term geological prediction of highway tunnel are illustrated.
