QUANTITATIVE ANALYSIS AND THREE-DIMENSIONAL GRAPHICS VISUALIZATION METHOD OF CROSSHOLE SONIC LOGGING DATA USING TOMOGRAPHY

摘要

tomography of the present invention is based CSL (Crosshole Sonic Logging) test data for quantitative analysis and 3D visualization relates to , the physical quantity obtained from CSL checking ( watching and amplitude ( or energy ) ) stored in the computer and , by performing tomography by using a physical quantity on each of the scan paths at regular intervals peg ( or file ) sound region and the defect of the cross section this region was estimated to be imaged with the 3D and 2D show a visible , by calculating the speed ratio of the cross-sectional area significantly less defective portion is characterized in that a quantitative analysis of the soundness of the pile . By doing this, ( the XY axis) cross section of the pile is somewhat size in any location and type of defect can be seen occurred .
