Application of Supersonic Wave Layer Separation Imagery Technique in Engineering Quality Inspection

Foundation treatment,expecially grouting effect test,Usually,it have greater limitations when use the testing methods such as core drilling,hydraulic pressure test,bore-hole televiewer,it is difficult to conduct a full scale and accurate quality evaluation.This paper describes the examples of the application of ultrasonic tomography method in such "hidden project" construction quality test,and concluded accurate velocity profiles,the physical properties is quantified,using data to prove,it is also facilitated to statistical analysis,the test results can be as a guide to construction treatment and engineering design.
