摘要
随着21世纪人类城市化建设的发展,城市环境地质研究成为水工环地质研究领域的一个重要组成部分,城市建设中的最主要问题是水资源问题和环境地质问题。城市水资源问题有:城市后备水源地的研究,以及应急水资源地和地下水库的研究。城市环境地质问题主要包括:(1)围绕城市建设和发展的一般性资源、地质环境问题;(2)城市地质作用产生的地质环境问题;(3)城市人口密集区及工业区的土壤和水体有机污染问题。解决城市环境地质问题的关键是对地下空间地层岩性及构造条件的研究,通过这些基础条件研究分析城市地质环境和地下水资源问题。可视化研究技术通过对城市地质体在地下空间的相对位置、形态、物化特征等三维构模处理,使这些城市赖以存在的地质基础条件可为非专业的决策层所理解,并在城市发展的规划中体现这些大自然所赋予人类的地下空间资源的价值。应用三维可视化技术对城市环境地质研究是一个全新的研究领域,目前尚没有系统完整的应用先例。三维可视化技术将在城市化环境地质研究中,开拓一个崭新的环境地质研究时代,成为城市环境地质研究的发展方向。
With the development of human urbanization in the twentieth ce nt ury,urban environmental geo-logical research has become an important compone nt part in the area of hydrological,engineering-geologi-cal and environment al-geological research.Water resources and environmental geology are the cruci al prob-lems in urban construction.The problems of water resources include reserve water resources,urgently needed water resources and subsurface water re servoirs.The problems of urban environmental geology in-clude:(1)the gen eral problem of water resources and geological environment about urban constr uction and development ,(2)the problem of geological environment resulting from urban geological effects,and(3)the problem of organic pollution of s oil and waters in densely inhibited districts and industrial areas.The key to s olving 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 subsurfa ce water resources can be analyzed.By means of 3D structural model treatment of the relative position,configuration and physico-chemical features of th e urban geologic bodies in the sub-surface space,visualization technology can make basic geological conditions for city subsistence understood by unprofessi onal decision makers and present in urban developmental planning the value of subsurface geo-logical resources with which nature endows mankind.The applica tion of 3D visualization technology in the study of urban environmental geolog y 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 environme ntal geological study and is a direction of research for urban environmental g eology
