水电三维地质模型中各地质要素的建模方法

Study on modeling of geological elements in hydropower engineering 3D geological model

决定水电工程地质分析成败的主要环节是地质实体的模拟。用三维数值地质实体模型来模拟实际工程施工过程,可以协助解决各种工程地质问题。介绍了水电工程中地质模型的各个要素(地形面、基岩面、岩层界面、构造界面、透镜体、地层单元、勘探工程以及地质实体)的创建方法、实现思路以及可视化显示,基本包含了水电工程地质分析所涉及到的所有方面。

Simulation of 3D geological entities was a key to the analysis of hydropower engineering geology. It could help to solve various problems on engineering geology and to simulate actual construction process with the numerical model of the geological entities. The authors presented creation of methods, realization ideas and visualization of various geological elements in the field of hydropower engineering, such as terrain surface, bedrock surface, stratigraphic and lithologic boundary, structural surface, lens, stratigraphic unit, exploration project and geological entity. The above elements basically covered almost all the elements of hydropower engineering geological analysis.
