Under the influence of rainfall and engineering excavation, it appeared the phenomenon of different sizes deformation, which affected the security during the construction and operation engineering seriously.
In the factors of affecting the slope stability or contributing landslide, the main internals are poor engineering geology conditions and rock structure conditions.
Therefore, a series of experiments have been conducted to combine engineering practice..

Abstract—GPSRTK and depth sounder technology provides a foundation for outdoor digital sampling of waterway dredging quality inspection.
We gathered the data under the Standard for Quality Inspection of Port and Waterway Engineering Construction.
The case study shows that Surfer’s volume calculation error is far lower than the 3% relative error of National Engineering Standard.
The reliability of Surfer’s volume calculation in engineering field is proved.
