摘要
介绍了探地雷达技术检测挡土墙完整性的基本原理。并结合工程实际,采用追踪识别法对所测探地雷达图像进行分析解释。分析结果表明,探地雷达这种无损检测技术能够较准确的完成挡土墙病害预报任务,包括厚度、含水量、裂缝、空洞等多种病害。
A new technique and its basic principle for assessing retaining walls integrality by ground penetrating radar are introduced. In virtue of actual project, the surveyed ground penetrating radar pictures are analyzed and explained by tracing and identifying method. The results prove that the non-destructive detection technique can exactly forecast the internal defects of retaining walls in time, including thickness, water capacity, fractures, holes and so on.
