地质雷达在梅河高速公路路基质量检测中的应用

Application of Ground Penetrating Radar on Quality Inspection of Roadbed at Meihe Expressway

地质雷达具有快速、连续、无损检测等优点,是近年来发展较为迅速、效果较为显著的检测方法之一。结合地质雷达在梅河高速公路路基质量检测的工程实例,通过分析几种典型的路基质量缺陷波形图像,从雷达检测路基的应用效果来看,使用该方法能够快速、准确地检测到路基下陷、路基不密实以及路基空洞等质量缺陷。随着地质雷达检测技术的不断完善和发展,地质雷达检测将成为路基质量评定中重要的环节之一。

Ground penetrating radar （GPR） has some advantages such as fast, consecutive and nondestructive detection. In recent years, GPR had gained fast development and remarkable effect. And so it has become one of the main detection methods. Based on an engineering application example of Meihe expressway roadbed quality detection, some typical defect wave images of roadbed quality were analyzed. From the application effect of radar roadbed detection, GPR can fast and adequately detect roadbed subsidence, unclose and hollow. With the continuous improvement and development of GPR, ground penetrating radar detection will turn to be one of key parts of roadbed quality evaluation.
