摘要
道路是一个城市最重要的基础设施,由道路地下空洞等引起的城市道路塌陷是当前道路养护面临的主要难题。地质雷达探测技术作为一种无损检测方法,以其方便、高效等优点被广泛地应用到城市道路病害探测方面。本文结合南京某建筑工程附近的道路塌陷隐患区探测工程实例,介绍了地质雷达在城市道路地下典型病害探测中的应用,并参考探测区域内的工程地质资料,对塌陷隐患区的形成原因进行综合分析,为后期病害治理和消险工程提供有力支持。
The urban road is the most important infrastructure of a city,and the urban road collapse caused by the un⁃derground cavity is the main problem of road maintenance.As a rapidly developing nondestructive testing technolo⁃gy,ground penetrating radar detection has been widely used in urban road detection because of its convenience and high efficiency.In this paper,combined with an example of a detection project for road collapse hidden danger areas near a construction project in Nanjing,the application of ground penetrating radar(GPR)in the detection of typical underground diseases of urban roads was introduced,and referring to the engineering geological data in the detection area,a comprehensive analysis of the causes of the formation of the hidden danger zone of collapse was carried out to provide strong support for the later disease control and risk elimination projects.
