Technical Field
[0001] The present application relates to the technical field of terrain structure establishment, and in particular to a method for establishing different terrain structures of a water conservancy project model. Background Art
[0002] The establishment of water conservancy project models is an important part of water conservancy scientific research and engineering design. It can simulate the actual terrain structure and hydrological conditions, and provide an important basis for engineering design and flood simulation. With the development of technology, the methods of establishing water conservancy project models are also constantly improving in order to more accurately reflect the actual terrain and hydrological characteristics. These models need to reasonably construct the actual terrain structure at a specific scale, and require relatively accurate simulation of different geographical locations to ensure that the experimental data in water conservancy projects can accurately reflect the actual situation.
[0003] At present, the methods for establishing water conservancy project models mainly include overall normal models, local normal models, generalized models or cross-sectional models. These models have detailed technical regulations in terms of geometric scale, reservoir simulation range, dam body materials and water flow resistance. For example, the geometric scale of the overall normal model should not be less than 1:300, and the geometric scale of the local normal model should not be less than 1:100. In terms of model making and installation, the terrain can be made using the cross-section panel method or the contour method. The spacing between model sections should not be greater than 100cm. The cross-sections can be encrypted or the contour method can be used for river sections with complex terrain. In addition, BIM technology and GIS technology have also been applied to the establishment of water conservancy project models. Through parametric design modeling, oblique photography three-dimensional modeling, point cloud filtering algorithm and other technologies, the construction of digital twins of water conservancy projects is realized.
[0004] Although the existing technology can simulate the terrain structure in water conservancy projects more accurately, there are still some problems in the actual operation process. For example, in the simulation experiment, it is necessary to reduce the actual topographic map according to the scale. The reduced shape is the same as the actual shape, but it needs to be constructed in multiple steps during production. This includes first making a white bar and marking the elevation. Then, after the sand is buried to a certain height, the white bar is inserted into the sand, and each position on the white bar is detected and adjusted in height so that each point corresponds to the actual mark. This process requires manual leveling of the sand pile according to the elevation so that the height of the sand pile corresponds to the elevation. Such operation is time-consuming and labor-intensive, reducing the efficiency of model construction. Summary of the invention
