| 摘 要： | 针对数值计算分析软件在建立复杂地质模型中人工简化过多、不直观等缺点,在研究曲面建模和体元建模的差别上,基于DIMINE软件建模平台,提出了使用DTM模型建立地表、线框模型建立地质体的三维地质可视化建模技术。在勘探平面图和剖面图的基础上,精确的建立了某矿区复杂三维地质模型,实现了任意剖面切割,为边坡稳定性分析提供了必要的参考。结果表明,该方法是可靠、有效的,为复杂地质三维模型提供了一种新的建模方法。

| Abstract: | Aiming at the disadvantages of too much simplification and lack of intuition of numeri- cal simulation software in establishing complex geology modeling, the differences between surface model- ing and voxel modeling were analyzed on the base of Software modeling platform. Then a new kind of method to eatablish 3D geological visualization modeling was proposed by using DTM model to build the surface and using wireframe model to set up the geological body. Based on the plans and sections of geol- ogy, 3D complex geological model of a mine has been built and its arbitrary profile cutting has been achieved, which provides the necessary reference to slope stability analysis. The result shows that this kind of method, which offers a new modeling method for 3D geological modeling, is reliable and effec- tive. |
