摘要：Based on cell complex theory, after analyzing the corresponding relationship among cell, cell complex and 3D spatial solid, a formal definition for 3D spatial solid is presented. Through analyzing the geometric constructing relationship between cell and cell complex, we induce element boundary define and adhesive relationship existed in 3D spatial object; analyse three kinds of non-manifold cases in three dimension, which are regarded as non-manifold adhesive relationship. And to express complicated 3D non-manifold solid and make sure the completeness and uniqueness of element topology information in model, relevant topological data structure is developed. Taking the surface and underground 3D space around University City region of Xianlin, Nanjing as the research object, a 3D model with complicated geological environment and man-made buildings is established based on the new presented 3D GIS data model, verifies the efficiency and application of the 3D GIS data model proposed in this paper
