Abstract
In this paper, the author researches on the tunnel engineering geological exploration system based on ground-penetrating radar. This paper complete exploration system design and production. System consists of adjustable signal source, voltage acquisition device, channel switching device, communication devices and current monitoring device. Exploration device is applied to experimental. A variety of geological conditions were simulated experiments. Complete measurement data acquisition. Measurement results are stored in the PC. Results of experimental verify the simulation. Through simulation and experiment can be found anomalies of resistivity changes will make changes in the electric field distribution. When resistivity of anomaly is certain, Changing in position and shape of the measured voltage value will be affect. The geological prediction theory of ground-penetrating radar is better understood. Simulation results help to research the real-time detection of abnormal response characteristics and detection results of the interpretation.
