Abstract
"(Article in Chinese only) - With the innovation and development of technology, BIM has been gradually introduced into dredging engineering. Dredging can be divided into waterway dredging and lake area dredging. In the waterway dredging project, according to the waterway depth data point, based on the BIM software----CIVIL3D, the 3D waterway terrain model can be established. At the same time, it can also be applied to the correction of the centreline in the early stage of the waterway design. Based on model, the practical control of waterway terrain can be realized by 3D cloud image analysis. Combined with the data of water depth over the years, the siltation of different waterways can be obtained quickly. In addition, the secondary development based on CIVIL3D solves the batch generation and drawing of dredging profile, and a lot of manpower can be saved and working efficiency can be improved. In the lake area project, the 3D land and water terrain model can be established by CIVIL3D according to the terrain elevation point and the lake water depth point. According to the design isobath of the lake bottom modeling, the design model of the lake area is established, and the corresponding filling and excavating quantity of the lake area is obtained through the 3D display and analysis, which provides the basis for the comparison and selection of the design scheme and the cost control of the different lake area. Based on the 3D land and the water model of the lake area, combined with the design model of the lake area, the excavating amount can be subdivided into the dry and the wet soil engineering quantity, and the dredging profile map of the lake area can be generated quickly. In this paper, it provides a case and experience for the application of the innovative technology of CIVIL3D in dredging engineering."
