Field testing
CT tomography software
SY8 cross hole Sonic logging analyzer software can display the three-dimensional tubular slice diagram, that is, the variation of the speed value of the external profile of the pile tested is displayed by using the chromatogram, and then the chromatogram is crimped and connected to form the tubular slice diagram to show the variation trend of the speed value of the pile body vividly.
The software can display the three-dimensional low-speed anomalous body diagram which can directly show the location and size range of low-speed anomalous body by the quasi-physical method. The pile can be controlled by the mouse to rotate along random direction and the positions of pile body can also be arbitrarily enlarged or shrunk to display the anomalous body in a more three-dimensional way.
The software can display the speed contour diagram, that is, the speeds of various profiles measured are displayed in the form of chromatogram, then the contour line can be drawn to form the speed contour diagram, and the range of speed values of various locations of pile body can be displayed specifically.
