地质雷达在京九铁路路基挡土墙质量检测与评估中的应用

地质雷达作为一种高分辨率、快速有效、数据实时处理及操作简便、无损的探测技术在路基挡土墙工程中得到应用,为质量评估提供完整、可靠的依据。主要介绍地质雷达检测挡墙墙体几何尺寸的基本原理、方法,以及在京九铁路路基挡土墙检测与评估中应用的分析和判断,认为该方法对结构物无损情况下可查清挡墙的内在缺陷,为尽早消除挡墙隐患和病害、确保行车安全起着十分重要的作用,具有显著的经济和社会效益。

GEORADAR AND ITS APPLICATION IN JING -JIU RAILWAY

The geological radar, the quick, effective and nondestructive inspection technology which has the advantage of high definition, real - time processing data and easy operation, has been used in subgrade retaining walls projects to provide reliable proofs for quality assessment. In this paper, the basis theory and method of evaluating the geometrical size of subgrade retaining walls are briefly introduced. Then it is brought forward that the technology has remarkable economical and social benefits, which can inspect the internal defects of retaining walls without damage of the primary structures and plays an important role on eliminating the hidden trouble of retaining walls and ensuring the safe driving, through the application of geological radar in inspecting and assessing the quality of sub-grade retaining walls of Jing - Jiu Railway.
