Application of Surfer in Quality Inspection of Waterway Dredging

Abstract:

GPSRTK and depth sounder technology provides a foundation for outdoor digital sampling of waterway dredging quality inspection. The gathered sample data can be used by Surfer to develop a 3D underwater topography model. Surfer can create 3D visualization through 3D space analysis, makes precise calculation of underwater earthwork load possible. Based on the Hangzhou-Ningbo canal dredging project, this paper describes the applied work principle and procedure of Surfer in quality inspection of waterway dredging. The technical aspect of cross section surveying and quality inspection is also analyzed. Surfer can adopt Trapezoidal Rule, Simpson’s Rule and Simpson’s 3/8 Rule to calculate volume. This paper performs error analysis on the results of each algorithm and proves the accuracy, reliability and efficiency of Surfer in waterway dredging quality inspection.
