| Abstract: | The priciple test technology in site of ultrasonic transmission method for detecting integrity of large-diameter cast in place piles are introduced. Through in-situ detecting some engineering examples, some characters of ultrasonic parameters of piles with defects are given. The detected results show that the method can judge and identify several defects of a long pile, and moreover the positions of piles defects exactly. |
