摘　　要：水利水电工程坝址区多位于河谷深切地形地段,两岸多山高坡陡,地形地貌、地层岩性、地质构造比较复杂。随着科技的进步以及工程的需要,三维协同设计及工程三维建模的相关技术软件带来的便利逐日突显,不仅体现内容丰富、质量好、效率高,更能从三维设计的角度反应现场的真实性,从而进行科学化工程设计。该文探讨在德隆水库工程坝址区地形、地层岩性、地质构造较复杂的情况下,对三维地质建模中的各种模型、地质结构单元建模顺序作合理的分析思考后,可提高建模精度和工作效率。The dam site of water conservancy and hydropower projects is mostly located in the deep topography of the river valley,with high mountains and steep slopes on both sides,and the topography,stratum lithology and geological structure are more complex.With the progress of science and technology and the needs of engineering,the convenience brought by the related technical software of 3D collaborative design and engineering 3D modeling is highlighted day by day,which not only reflects the rich content,good quality and high efficiency,but also reflects the authenticity of the site from the perspective of 3D design,so as to carry out scientific engineering design.This paper discusses the reasonable analysis and consideration of various models and the modeling sequence of geological structure units in three-dimensional geological modeling under the condition of complex topography,stratum lithology and geological structure in the dam site of Delong reservoir project,thereby can improve the modeling accuracy and work efficiency.
