三维探地雷达技术在道路塌陷空洞探测中的应用
|
摘要
道路塌陷空洞一直是威胁交通安全运行的重要隐患,对道路塌陷空洞的探测方法进行研究具有重大的现实意义。研究工作通过实例探讨三维探地雷达(GPR)对道路塌陷区进行探测的方法技术及其应用效果。为查明道路塌陷空洞的空间分布特征,在塌陷区布设了共23条测线,1.0 m×0.5 m的三维测网并进行数据采集;通过对雷达数据进行处理,获得不同测线、不同方向的三维雷达剖面。结合地质情况对上述图件进行综合分析与解释,准确地查明塌陷空洞的位置、埋深及发育程度;经开挖验证,解译结果可靠。工程实践表明,三维探地雷达技术可以快速、高效地应用于道路塌陷探测中,其探测结果可为塌陷区后续施工以及安全防治提供参考。
The road collapse has been a serious threat for safety of the traffic, and it is of great practical significance to study the detection method of road collapse. This paper analysis the technique and its application of three dimensional ground penetrating radar(GPR) for detecting certain road collapse. In order to find out the spatial distribution characteristics of the road collapse zone, the 23 survey lines are set up in the collapse area by a observed mesh with size of 1.0 m × 0.5 m, the data collection are carried out. The observed GPR data are processed by conventional method and the two and three dimensional radar profile were obtained. The comprehensive analysis and explanation of the processed profile are conducted with the geological condition, and the location, depth and development of the collapse are accurately found which proved that the interpretation results are reliable. Engineering practice shows that the application of three dimensional GPR can be rapid, and efficient in road subsidence detection, the detection result can provide key reference for prevention and control of subsidence of subsequent construction and safety.
