Automatic Modeling Algorithm Research And Application Of Complex Structural Geology In Three-dimensional Space

With computer science, computer graphics and modern mathematical theories of development and innovation, three-dimensional model of underground space of geological research in the field has become hot. Three-dimensional geological modeling in the 20th century and early 90's began to attach importance to human beings, and has become mathematical geology, petroleum exploration, geotechnical engineering, GIS, and scientific computing research in the field and application of hot spots. At present a simple model of layered structure of the geological bodies already have built more mature solution, while the fault structure model of the building is three-dimensional model of the geological structure of the key difficulties and also the current research focus related to academics.In this paper, "Automatic modeling algorithm research and application of complex structural geology in three-dimensional space" as the subject of background, engineering geology in three-dimensional modeling algorithm are the key issues have been studied, mainly in the following areas:(1) This paper studies the characteristics of geological data, based on the characteristics of fault structures for the design of three-dimensional structure of a typical fault terrain models, including the plane model, oblique plane model, parabolic model, given various typical model build process ;(2) Ordinary Kriging interpolation algorithm as the original data interpolation to obtain a relatively accurate, complete three-dimensional solid model can not be applied with a special terrain, so this must be in accordance with landscape design unique local Kriging method to discrete regions in different geologic. The survey data interpolation processing, the formation of the regional rules of grid data to form a triangular network, fault-based TIN terrain model;(3) Through the changes of the parameters in geological modeling, as well as the calculation of the statistics of the relative error after interpolation the location of the special spots to determine a variety of terrain model, location, angle changes, the local interpolation algorithm is the scope of application of local interpolation algorithm is given the scope of application of the environment and at the same time, given the changes in the scope of the data error; (4) A typical fault established under this geological model, select Microsoft Visual Studio. NET 2003 as development platform, combined with development of high performance graphics library OpenGL, through the ADO components to connect SQL Sever2000 attribute database, through the connection to the database, to extract from the database to establish geological model-related data, to achieve real-time modeling of geological data and model the dynamic update capabilities.Construction of this system of geological faults interpolation algorithm, not only realized the special geological interpolation processing, also gives the local interpolation in a variety of terrain model of the scope of application in practice, the feasibility of the basic theory and in practice, the basis for further improved theory.
