英文摘要	An improved algorithm is presented to resolve intersection related problem of triangular surface in 3D geological modeling and analysis, using a structured data search algorithm to exclude most of non-intersected triangles away from intersecting line efficiently and accurately. And a new improved OBB search tree is built to obtain the intersection quickly; triangles near intersection are reconstructed optimized at last. Typical applications of 3D geological modeling using presented algorithm is researched, including of cutting geological model by parameter plane, faults and stratigraphic intersection and geological region discretization. Practice has proved that the method is fast and reliable by comparing to other several methods, especially has obvious efficiency advantages in surface intersection with large amount of data. And it has grate advantages in 3D geological modeling and analysis in surface intersection issues and providing an effective support in building geological model automatically. ? 2015 ejge.; EI; 21; 11507-11517; 20
