探地雷达在盾构施工中的应用原理和实验分析研究

Application theory and experiment study about ground penetrating radar for shield machine

分析探地雷达圆周成像原理和特点,对实验测量数据进行了数字处理以及正演模型,验证探地雷达圆周测量障碍物和土质分层中的可行性和有效性,为盾构应用实时探测研究提供有益的探索.

This paper presents a ground-penetrating radar (GPR) data acquisition method called circular scanning. Moreover, by using numeric processing to process the experimental data, we also use the radar wave simulation technique to compare with the data, which demonstrates that this methods can be used to detect the obstacles and stratums. All these work provide a meaningful exploration to real-time detection of the front of shield tunnel boring machines.
