碩士 === 國立中央大學 === 應用地質研究所 === 89 === Tomography is an image technique which generates a cross sectional picture of an object by utilizing the object’s response to the nondestructive, probing energy of an external source. Nowadays the theories and techniques of tomography have been well developed and applied to a number of fields such as Medicine. However, this technique is not well applied in geology and civil engineering. Making correct images of civil infrastructures and subsurface stratigraphy still have plenty of rooms for improvement. This research stresses on the ground penetrating radar (GPR) survey using tomography technique to civil engineering problems. The present philosophy is based on the travel time and amplitude of GPR. Using picture program establishes the image of the samples and color bar expresses the distribution of the parameters, a tomogram is formed. Then we can learn the structure of the cross section of an object. The results indicate that the tomographic GPR is superior to the traditional methods for non-destructive testing of the infrastructure or geology mapping.
