基于走向控制和产状约束的三维地质建模方法
A structural modeling method constrained by strike and attitude
摘要
Abstract
To address the challenges of three-dimensional(3D)geological modeling caused by insuffi-cient basic data and complex geological structures,this paper proposed a novel structural modeling meth-od based on accessible planar geological maps.A batch generation algorithm for structural surface con-trol points,constrained by strike orientation and formation attitude,was developed to automatically con-struct triangulated irregular networks of structural surfaces.Additionally,based on computational geome-try techniques,including the collision detection of axis-aligned bounding boxes,an algorithm for recon-structing spatial topological relationships was proposed.This method constructs the contact relationships between structural surfaces and establishes the topology of fault networks,thereby forming a comprehen-sive methodology from data generation and storage to 3D model construction and visualization.Practical applications demonstrate that the proposed method effectively addresses the issue of insufficient funda-mental data in 3D geological modeling,and is thus capable of accurately constructing 3D geological models for special structural areas such as fault networks and steeply inclined strata.The method,char-acterized by its simplicity and ease of implementation,offers a valuable supplement to the 3D geological modeling method system.关键词
