探地雷达探测地基病害的应用研究
摘要:在探地雷达理论的基础上,结合工程实例,阐述了探地雷达在探测基坑开挖引起的地基病害中的应用。通过分析地基病害产生的机理,归纳了地基病害如土体疏松、脱空和滑移在雷达测线剖面图和单道波形图的典型图像特征,并判定出地基病害的程度和空间位置,工程还采用现场开挖及静力触探对比验证探地雷达的探测结果;实践证明了探地雷达技术是一种有效的地基病害快速探测方法,值得大力推广。
Abstract:On the basis of the radar theory, combined with the engineering example, this paper expounds the application of GPR in the detection of foundation pit excavation in the disease. Through the analysis of the mechanism of foundation diseases, summarizes the typical characteristics of the soil foundation diseases such as osteoporosis, image separation and slippage line profile measured in the radar chart and the single waveform, and determine the extent of disease and the spatial position of the foundation, the project also uses the site excavation and penetration test of ground penetrating radar detection results; practice has proved that the ground penetrating radar technology is an effective method for rapid detection of foundation diseases, it is worth to popularize.
