混凝土结构雷达检测中的钢筋相互干扰研究

Studies of rebar interactions in concrete structure surveys using GPR method

探地雷达目前已被广泛地应用于土木工程领域,但其在钢筋混凝土结构中的应用并不多,主要的原因是混凝土内配筋复杂,相邻钢筋对雷达波有很大的干扰,使雷达图像难以辨识。为更好地识别复杂配筋下的雷达图像,找出其雷达图像特征,研究了各种相邻钢筋的雷达图像并得出了一些对钢筋混凝土的雷达检测有益的结论。

Ground Penetrating Radar （GPR） is widely used in civil engineering, but there are few field applications in concrete structures. It mainly dues to the complex rebar groups in the concretes. This rebar groups make the radargrams hard to be recognized. In order to find the radargram features of this rebar groups,we stepped into the test studies of the rebar interactions and we got some instructional conclusions.
