探地雷达在道路脱空空洞病害检测中的应用
|
摘要
探地雷达能够快速、高效、无损地进行地下目标探测,是浅层地球物理勘探的一种重要工具,已成为城市道路病害检测的首选技术手段,但由于地下目标所处环境较为复杂,且地下脱空、空洞呈现的形态差别大,形成原因各异,在实际探测中对地下脱空、空洞的识别较为困难,且缺少有效的探测方法,本文根据近两年兰州市市政道路塌陷实际情况,结合本地地质、地下设施及环境因素研究分析了本地地下病害的形成原因,并介绍了探地雷达在道路病害检测方面的方法技术及数据处理分析的经验和难题,且以实例阐述了该方法的应用成果。
Ground-penetrating radar can detect underground targets quickly,efficiently and without damage.It is an important tool for shallow geophysical exploration and has become the first choice for urban road disease detection.However,due to the complex environment and underground environment of underground targets The morphological differences between voids and voids are large,and the causes are different.It is difficult to iden-tify underground voids and voids in actual exploration,and there is no effective detection method.According to the actual situation of municipal road collapse in Lanzhou in the past two years,combining with local geology,underground facilities and environmental factors,this paper analyzes the causes of the formation of local underground diseases,and introduces the methods and techniques of ground penetrating radar in the detection of road diseases and the experience and problems of data processing analysis,and the application results of the method are illustrated by examples.
