摘　　要：该文主要探究基于三维地质模型的岩土工程设计要点与可视化实现方法。通过平剖面拉伸、旋转的方法构建基坑体三维模型,使用GTP建模方法构建地质体三维模型,运用拓扑无缝集成原理和三角形自分解算法实现地质模型与基坑模型无缝集成,为岩土工程基坑的无缝开挖提供支持。同时提出一种基于纹理映射的可视化技术,分别对地层体和基坑开挖体进行纹理映射,可保证三维地质模型的真实感和可视化,在指导岩土工程的设计与施工方面发挥良好效果。This paper mainly explores the key points of geotechnical engineering design and visualization realization methods based on three-dimensional geological models.The three-dimensional model of the foundation pit body is constructed by stretching and rotating the plane section,and the three-dimensional model of the geological body is constructed by using the GTP modeling method.The seamless integration of the geological model and the foundation pit model is realized by using the topological seamless integration principle and the triangular self-decomposition algorithm.It provides support for the seamless excavation of geotechnical engineering foundation pits.A visualization technology based on texture mapping is proposed,which maps the stratum body and the foundation pit excavation body respectively,ensuring the realism and visualization of the three-dimensional geological model,and playing a good role in guiding the design and construction of geotechnical engineering.
