探地雷达检测混凝土内含水量梯度
Inspection of Water Content Gradients in Concrete with Ground Penetrating Radar
摘 要
由于水分是引起混凝土劣化的主要原因之一，混凝土含水量的检测问题也成为近年来的研究热点。利用材料的毛细管效应设计了一个吸水试验装置来模拟混凝土中的水分传递。其主要目的是通过电磁（EM）导波监测水分在混凝土板中随时间的变化过程。混凝土的渗吸试验中使用了新的经验模型arctan（x），且以γ射线的测量结果作为试验的参考数据。结果显示，融合使用多层波导（WG）模型和探地雷达（GPR）检测，可以有效估计混凝土板的内部梯度曲线。

Abstract
In recent years, many studies have been done on concrete about the detection of its water content, since it is one of the main causes of degradation. In this study, an experimental set-up of imbibition by capillary effects is used to model the water transfer in concrete. The main objective is to monitor the water transfer through time by electromagnetic (EM) guided waves. The new empirical model-arctan(x) was applied to the experiments on concrete slabs of imbibition. The water content distributions measured by gammadensimetry are set as reference. The results show that the combination of the multi-layer waveguide (WG) model and ground penetrating radar (GPR) measurements allowed to estimate the gradient curves inside concrete slabs.
