Research on 3D Dredged Soil Visualization Analysis of Qinhuangdao Harbor Project

摘要

In order to rapidly, accurately and vividly provide plenty of underwater soil analysis information for design and construction in dredging engineering, this paper took Qinhuangdao harbor project as an example, introducing a three-dimensional underwater soil modeling method and establishing the 3D unified soil solid model of Qinhuangdao harbor. The model has a small amount of data storage, high precision and is easy to operate graphical computing. Based on the model, and with 3D visualization technology, a series of soil visual analysis were conducted, including virtual digital drilling, arbitrary cutting analysis and water depth elevation analysis. Moreover, the model could quickly output scene graph, 2D cross-section and isoline map. Practical engineering applications indicate that 3D dredged soil visualization helps engineers to understand the space distribution of underwater soil. The proposed method can provide a convenient support tool for dredging engineering soil analysis.
