【摘要】 岩土工程建设所需的各种工程地质信息的有效管理直接影响到了工程的顺利进行和建设效率的提高。同时,信息的三维可视化表达对工程分析和决策具有直观的辅助作用。因此,对它们的研究和探讨具有一定的工程实用价值和理论意义。本文就多源工程地质信息的GIS管理和三维可视化表达的一些关键问题进行了深入的研究,主要包括：(1)工程地质信息的采集、分析和融合等问题的研究为了有效地管理各种工程地质数据,有必要通过一些基本问题的探讨来对不同工程地质信息的内容及用途进行明确和归纳。(2)工程地质信息建模及其GIS空间数据模型的实现使用信息建模的手段对各种工程地质信息的内容、相互间的联系和功能等进行抽象,并通过GIS空间数据模型将工程地质信息模型实现为具体的物理结构,为基于GIS的信息管理提供数据准备。(3)工程地质信息的GIS管理功能的分析和实现分析了所需要实现的工程地质信息的GIS管理功能,并以ArcGIS Desktop软件对其实现进行了探讨。(4)空间地质体边界建模的三维数据结构的设计基于常用三维数据结构的分析和地质空间的拓扑分析,设计了能够表达地质空间非流形拓扑关系的数据结构以及相应的拓扑操作。(5)地质层界面格网的递归插值生成算法的设计研究了主要的曲面插值、拟合与细分方法,将离散光滑插值方法与Loop三角格网细分相结合,设计了一种适用于地质层界面三角格网递归插值细分的算法。(6)工程地质信息建模流程方法的研究(7)工程地质信息管理与可视化系统的设计和实际工程应用更多还原

【Abstract】 Effective management of various geological information required by geotechnical constructions will directly affect whether the construction is smooth going and improvement of construction effects. At the same time,3D visualization representation of information will help construction analysis and decision. For these reasons, it has certain practical value and theoretical significance to construction to study and discuss them. Some key problems of GIS management and 3D visualization representation of multiple sources geological information are discussed in this paper, which are mainly including:(1) the research of collection, analysis and integration of geological informationFor effectively managing various geological data, it is necessary to clear and sum up the content and use of geological information through discussion of basic problems.(2)geological information modeling and its implement of GIS spatial data modelThe content, relations and functions of various geological information are abstracted by using the method of information modeling. And geological information model turn to physical structure through its GIS spatial data model. It provides data preparing for GIS information management.(3)the analysis and realization of GIS management functions of geological informationGIS management functions of geological information are analyzed. And the realization of these functions is discussed through the software ArcGIS Desktop.(4)the design of 3D data structure of spatial geologic solid B-rep modelingBased on analyzing 3D data structures and the topology of geologic space, the data structure which can represent topological relationship of non manifold of geologic space and the appropriate topological operations are designed.(5)the design of interpolation recursion algorithm to build meshes of stratum interfaceThe main interpolation methods, fitting methods and subdivision methods are studied. An interpolation recursion algorithm of combining discrete smooth interpolation and Loop subdivision for building triangulation meshes of stratum interface is designed.(6)the research of the flow path and methods of geological information modeling (7)the design and application in the practical construction of geological information management and visualization system更多还原
