Study on the Application of CT in a Grouting Effect Test of Super-Long Piles
2014
Wave velocity is the main physical parameter of an ultrasonic wave CT test; it can distinguish the change of strength and density in a reinforced section. The absorption coefficient is the main physical parameter of electromagnetic CT; it can determine the distribution of the reinforced section. CT was applied to evaluate the grouting effect of group piles in the Su-Tong bridge. According to the results of coring and the CT test, it is practicable to apply ultrasonic wave CT and electromagnetic CT synthetically to test the grouting effect of super long piles.
