摘要

摘要: 如何快速、准确地建立地质体的三维模型一直是众多岩土工程数值模拟工作者所面临的难题。虽然三维地学模拟软件具有很好的三维地质建模能力,但是由于数据结构的差异,采用他们现行三维地学模拟软件建立的地质模型难以导入数值模拟分析软件中,以为相应工程问题的数值模拟服务。目前,随着各种CAD、CAM软件行业的的飞速发展,涌现出了许多优秀的三维建模软件,而且这些软件大都与现行数值分析软件有着良好的数据接口功能。据此,本文提出了采用现行CAD软件来建立工程地质体的三维模型,使得建立的模型达到既可视又可算的目的。将其应用于云南某高速公路边坡的三维建模中,证明了该法具有方便、快捷和合理等优点。

Abstract: How to build the three dimensional model of the geologic body quickly and truly is a difficult problem which lies in the front of the numerical simulation operators. Although the three-dimensional (3D) geoscience simulation software has good 3D geological modelling ability, it can be difficult to join the corresponding geological model established by 3D study simulation software with numerical simulation software because of the difference in data structures. A majority of CAD software have good data connection with the present numerical analysis software. This paper presents a study on how to use CAD software to establish 3D geological model for 3D visualization and numerical simulation purposes. The 3D modeling of some highway slopes in Yunnan is used an examples to illustrate this approach is convenient, accurate and reasonable.
