摘　　要：针对川东地腹褶皱强烈、逆断层发育、高陡构造等实际情况,提出将三维地质建模技术与射线理论相结合,发挥三维地质建模在描述空间拓扑关系的优势,为射线路径提供尽可能准确的地质模型,借鉴基于要素的建模技术,形成了适合于复杂构造的三维地质建模方法,并在此基础上,提出了处理射线多路径和多值面方法。To cope with the strongly folded strata,well developed thrust faults and highly steep structures in the eastern Sichuan area,this paper put forward a method for 3-D geologic model building based on element model method.The method combines 3-D geologic modeling with ray theory,and takes full advantage of 3-D geologic modeling in describing spatial topological relations.Methods for dealing with ray multipath and multivalued surface were presented.
