探地雷达以其高效、无损、可靠、工作条件宽松等特点,在工程领域中的应用日趋广泛。但市政工程电磁干扰较多,给以电性差异为前提的探地雷达勘探造成很大影响。地下障碍物、路基病害、隧道衬砌质量等市政工程的检测表明,经过现场试验,选取尽可能合理的观测参数,探地雷达仍可在市政工程中达到较好的效果。
Ground penetrating radar is widely used in engineering field due to its characteristics of high efficiency, nondestructiveness, reliability and relaxed working conditions. However, there are more electromagnetic interferences in municipal projects, which have a great impact on ground penetrating radar exploration based on the assumption of electrical differences. The detection of underground obstructions, roadbed diseases and tunnel lining quality and other municipal works shows that ground penetrating radar can still achieve better results in municipal engineering after field test and selection of observation parameters that are as reasonable as possible.
