Abstract
Abstract: With the development of human urbanization in the twentieth century, urban environmental geological research has become an important component part in the area of hydrological, engineering-geological and environmental-geological research. Water resources and environmental geology are the crucial problems in urban construction. The problems of water resources include reserve water resources, urgently needed water resources and subsurface water reservoirs. The problems of urban environmental geology include:(1)the general problem of water resources and geological environment about urban construction and development, (2)the problem of geological environment resulting from urban geological effects, and (3)the problem of organic pollution of soil and waters in densely inhibited districts and industrial areas. The key to solving the urban environmental geological problems is research on lithological and structural conditions in subsurface space. Through a study of these basic conditions, the problems about the urban geological environment and subsurface water resources can be analyzed. By means of 3D structural model treatment of the relative position, configuration and physico-chemical features of the urban geologic bodies in the subsurface space, visualization technology can make basic geological conditions for city subsistence understood by unprofessional decision makers and present in urban developmental planning the value of subsurface geological resources with which nature endows mankind. The application of 3D visualization technology in the study of urban environmental geology is a frontier and up to now there is no systematic and complete precedent for its application. 3D visual technology will usher in a new epoch of environmental geological study and is a direction of research for urban environmental geology
