【Abstract】 As a detecting method,GPR can nondestructively detect unknown underground obstacles and evaluate the quality of engineering basements. GPR method has developed rapidly in recent years. It is fast .accurate,economical and nondestructive. By the application of detecting the position of steels in concrete .high frequency GPR detects the layout of steels in walls successfully including the thickness of concrete and its protecting layer,the number of steels and the distance between steels and so on. As a result,the application of GPR can supply more accurate intensity parameters for design and construction units.更多还原
