[Abstract]:Through the research and analysis of the whole engineering of earth-rock dam and the structure of the prototype component of earth-rock dam, according to the method of CAITA skeleton design, the three-dimensional prototype model of earth-rock dam is established. The 3D prototype model is developed with C # programming language, combined with the three-dimensional model browser and other plug-ins. The interactive operation and demonstration of 3D model and virtual teaching are realized, and finally a demonstration system of earth and rock dam design teaching is formed. The main contents of this paper are as follows: (1) the 3D prototype parameterization of earth-rock dam is divided into basic components of earth-rock dam, based on the basic theory of parameterization, and according to the basic rules of parameterized design. Various parameters of earth-rock dam components are extracted, including geometric parameters, assembly parameters, mechanical parameters and material parameters. Finally, parameterization of all components of earth-rock dam prototype, including dam top, dam body, slope protection, seepage prevention body and drainage facilities, is realized. It provides parameter support for the establishment of 3D parameterized model of earth-rock dam. (2) Three-dimensional modeling method and model interaction research. Through the research and analysis of the whole engineering of earth-rock dam and the prototype structure of earth-rock dam, Combined with CAITA skeleton design method, the integral skeleton model and cross-section skeleton model of earth-rock dam are established, and then the template library of earth-rock dam component is established by CATIA.
