| 摘 要： | 从苏锡常地区地面沉降研究实际需要出发，介绍了利用虚拟现实技术构建地面沉降地质结构三维可视化模型虚拟现实系统的设计思路、开发模式、实现方法和功能特点。该系统真实表达了研究区三维地层结构特征，逼真再现了地面沉降模型所预测的地下水流场、地面沉降发展变化过程，并虚拟表现出地面沉降可能造成的后果，为苏锡常地区地面沉降机理及预测研究提供了一个全新的三维可视化平台。

| Abstract: | According to the practical requirement of studying land subsidence in Suzhou-Wuxi-Changzhou area,three dimensional land subsidence virtual reality system is developed.The authors depicted some details,including design frame,develop mode,method and functions,about this 3D land subsi-dence virtual reality system which is constructed by utilizing the virtual reality technology.By making use of this system,3D geological structure can be simulated,the groundwater flow field and the dynamic process of land subsidence,whose metadata are calculated by the land subsidence model,also can be vividly expressed,at the same time the sequent of land subsidence also can be virtually displayed.In a word, this virtual system would act as a visual platform for studying the mechanism and forecasting of land subsidence in Suzhou-Wuxi-Changzhou area. |
