介绍应用探地雷达检测挡土墙厚度的原理及技术 ,阐述该技术的基本方法及其数据图像处理过程。通过一工程实例检测 ,表明该技术对挡土墙检测是可行的。其检测误差在 5%以内 ,对回填层密实程度也可作出粗略估计。
The principle and technique of using GPR to detect the thickness of retaining wall are introduced. The basic method of this technique and its data image processing are introduced. Through an engineering example test, it shows that this technique is feasible for retaining wall detection. The detection error of less than 5%, the density of the backfill layer can also make a rough estimate.
