摘要
通过对地质雷达工作原理的理论基础分析,重点对天线频率的选取、数据采集的质量提高,典型雷达图像的解释方法等进行了介绍。并结合具体的隧道工程实例,分析了隧道中裂隙带及富水带在雷达图像上的特征,验证了采用地质雷达的方法在隧道工程中进行超前预报的准确性和重要性。
Based on the working principle of ground penetrating radar,the antenna frequency selection and the data collection precaution are focused on in this paper.The typical radar images explanation is also introduced.Combined with specific examples the features of typical radar images of the fractured zone and water enriched zone are analyzed and the forecast in accuracy and efficiency of GPR in tunnel is verified.
