探地雷达在城市交通建设中的技术应用

摘要

The complex conditions encountered in the construction of urban rail transit engineering are increasing, so the geological conditions of the project need to be explored and determined with high accuracy. In recent years, ground penetrating radar (GPR)plays an important role in the exploration of underground space. The paper discusses that the ground penetrating radar (GPR) is used to explore the urban rail transit construction project.The cor-responding understanding on the typical underground anomalous body encountered is obtained through the data acquisition,the reac-tion on the profile for the anomalous body and the interpretation of the results, which can provides reference for the similar under-ground space engineering conditions. The practice shows that the ground-penetrating radar can be applied to the detection of anoma-lous bodies in urban engineering.%城市轨道交通工程建设施工中所遇到的复杂施工条件增多,需要对工程地地质条件进行高精度的探查与判断.近年来探地雷达作为一种高新地球物理探测技术在地下空间条件探查中发挥了重要作用.采用探地雷达技术,在某城市轨道交通建设工程中进行探查实践.对所遇到的典型地下异常体进行探查与分析,在数据采集、异常体在雷达剖面图上的反映以及结果解释等方面获得了相应的认识,可为同类地下空间条件探查提供参考.实践表明,探地雷达可应用于城市工程中的异常体检测.
