A Study of Flaw Detection in the Concrete Structure Using Geophysical Prospecting Method

물리탐사법을 이용한 콘크리트 구조물의 결함조사에 관한 연구

Various nondestructive prospecting method were applied to detect the flaws of concrete structure, but the satisfactory result could not be obtained, yet. Fracture and cavities existing concrete structure will have a bad effect on physical and mechanical characteristic of concrete. This study deal with detection of flaws using seismic first arrival and various inversion method in theoretical model. And ultrasonic seismic method is tried to experimental model to detect fracture and cavity.
