Ground penetrating radar in crack detection to the forward research

摘要

The ground fissure is hidden hazards of ground deformation. Survey work to crack is the basic of control measures. Geological radar detection as an emerging technology has advantages of rapid, continuity and visibility; according to a practical example of the detection mechanism of landslide cracks, summed up the ground fissures radar image features. Using numerical simulation method to establish a three-dimensional numerical analysis model, to get to distribution and extension of the crack, the study shows that the results of numerical simulations and field surveys are the same. The results of geological radar detection are accuracy, and provide control of ground fissures a scientific basis.
