水利水电三维地质模型覆盖层建模技术研究
Research on modeling technology of overburden layer for 3D geological model in water resources and hydropower projects
摘要
Abstract
In recent years, building a 3D geological model for water resources and hydropower projects has become a new useful method for geological workers to know layer structure and analyze geological phenomenon. Based on CATIA software, a 3D geological modeling platform is built using Visual Basic.net language, which contains several basic modules, such as overburden layer, geological layer, hydrological layer, model analysis, model cutting, finite element analyses, etc. Based on the 3D geological modeling platform developed by authors, the modeling process for overburden layer is proposed. Some key technology issues are analyzed in detail, such as original data processing, surfaces splitting and surface stitching. Besides, the platforms have the functions of quality testing and repairing work for building 3D geological model which guarantee the reliability of the model. At last, a 3D geological model is built using 3D modeling platform to simulate the geology for a hydropower station. 2D figures can be exported by cutting the model at any angle and anywhere in 3D space to satisfy the designing requirement in engineering.关键词
