一种含断层的复杂层状地质体三维自动构模方法研究
Study of 3D automatic modeling method of complex geological layer including faults
摘要
Abstract
In order to automate and simplify the process of complex geological object modeling, based on analyzing the spatial characteristics of complex geological layer, a new automatic modeling method which aims at the geological layer including faults is put forward. This method firstly preprocesses the geological drilling material and geologic report figure to get the data of discrete points; the data will be stored in a database. Then choosing a modeling method based on surface model, the top surface and bottom surface models of the geological entity are established separately in the process that originates from borehole stratified information to profile map and ends up at geologic surface. According to the topological space, the method constructs faults with their fault lines and insets them into the original surface. Finally, by using contour line joining to generate the side-surface, it sutures those surfaces into a closed 3D geological object model. A 3D visualization system which is developed independently is used to verify this method, and it is successfully put into use to construct the 3D geological modeling of a coal mine in Shanxi Province. Experiment shows that the method is fast and efficient with high automation; the effect of the constructed model that expresses complex geological structure is good.关键词
