三维雷达探测技术在广西高速公路预防性养护中的应用研究
Applied Research of 3D Radar Detection Technology in Preventive Maintenance of Guangxi Freeway

本文分析了高速公路传统养护方面存在的问题，论述了预防性养护的比较优势，建议在高速公路预防性养护中采用三维雷达技术对路面潜在病害进行定期动态检测，防患于未然。作者分析了路面病害类型及成因，介绍了三维雷达技术原理、探测方法，选取广西高速公路典型路段作为试点，采用新加坡DECOD三维探地雷达设备进行探测。本文经过数据处理，结合图像识别经验，得到相对准确的探测成果，可为后续精准养护设计施工提供重要参考。本次试点探测有助于推广广西高速公路预防性养护的理念，降低路面维修成本，提高使用寿命和综合效益，进而提升高速公路出行幸福感。
This paper analyzed the problems in the traditional maintenance of freeway, introduced the comparative advantages of preventive maintenance, and suggested that 3D ground penetrating radar be used for regular dynamic detection in the preventive maintenance of the Guangxi freeway to find the potential problems of road surface and prevent accidents before. The authors analyzed the types and causes of pavement distress, introduced the principle and detection method of 3D radar technology, and selected typical sections of the Guangxi freeway as the pilot to detect by the Singapore DECOD 3D ground penetrating radar equipment. This paper obtained relatively accurate results through data processing and image recognition experience, which would provide a valuable reference for the accurate maintenance design and construction subsequently. This paper would help to promote the concept of preventive maintenance of the Guangxi freeway, reduce the maintenance cost of road surface, increase the service life and comprehensive benefits, and enhance the freeway users’ sense of happiness finally.
