摘要
探地雷达是岩土工程检测中较为经济、高效检测工具之一,在检测混凝土内钢筋的位置与数量方面的应用效果与钢筋的直径及间距以及天线分辨率有很大关系,文章利用900MHz天线在检测隧道二衬中第一层钢筋的位置与数量具有良好的效果,但对第二层钢筋的检测效果不佳,钢筋相互干扰的问题仍是以后雷达检测中值得研究的方向。
Ground penetrating radar is one of the economic and efficiency method of geo-technique detecting method, the detection effective of rebar is relation with the space, diameter of rebar and frequency of the antenna, the effective of the detection of first layer rebar in tunnel is very good. But the affection of rebar each other is the study direction of the GPR detection.
