Abstract :
In Artificial Freezing Engineering(AFE), the distribution of freezing soil and its defects are important to engineering safety. Based on relative permittivity measured by vector network analyzer, electromagnetic models of artificial freezing walls were made. Then Ground Penetrating Radar (GPR) exploration of AFE was simulated by Time Domain Finite Element Method (TD-FEM) coupled with freezing temperature calculation. GPR were also used in AFE exploration. The research results show that GPR exploration and numerical simulation are in good accordance with each other.
