NDT Using Transmission Line Model to Identify the Defects in Pile Shaft
The behavior of piles having a single defect which may be necking, bulging or of inferior concrete is simulated by an electrical model representing an electrical transmission line. The model successively simulated defective piles embedded in homogenous soil. Through the interpretation of response curves supported by appropriate mathematical treatment it was possible to study piles having a single defect .The type of defect can be identified from the response curve by comparing the pile head stiffness of suspect pile with that of a similar but sound pile in the same site. The location of the defect can be determined by measuring the interval between resonating peaks at higher frequencies. For the same defect location along the shaft of piles in a given site, it can be differentiated between resonating large peaks for piles with bulging and necking.
