采用地质雷达对公路挡墙砌筑质量进行检测,可快速了解挡墙砌筑厚度、密实度等质量情况。在介绍地质雷达检测挡墙的基本原理、方法及检测过程中相关参数选择的基础上,探讨了影响检测结果的几个主要因素。实测资料表明,地质雷达法能够较好地反映墙体厚度和砌筑质量,与常规的检测手段相比具有操作方便、检测效率高的优点,可作为挡土墙施工质量检验的依据。
The use of geological radar to detect the quality of road retaining wall masonry, can quickly understand the retaining wall masonry thickness, density and other quality conditions. Based on the introduction of the basic principle and method of GPR retaining wall and the selection of relevant parameters in the process of detection, several main factors affecting the test results are discussed. The measured data show that GPR can better reflect the thickness of wall and the quality of masonry. Compared with the conventional detection methods, GPR has the advantages of convenient operation and high detection efficiency, which can be used as the basis for the quality inspection of retaining wall construction.
