摘　　要：提出了基于地理信息系统(GIS)的水利水电工程三维动态可视化仿真技术,实现图形辅助仿真建模、全过程动态仿真计算和基于GIS的仿真可视化。图形辅助建模采用层次化和模块化建模思想,通过组合图形元素建立模型,有效地降低了建模的复杂性。全过程动态仿真采用“双仿真钟”模式,兼顾了仿真的整体性和细节性,对整个施工动态过程进行仿真。用GIS实现仿真的三维可视化改变传统的仿真结果的表现模式,为施工系统分析和管理提供了一个有力的工具。实际工程应用证明了该方法的有效性。A GIS-based three-dimensional dynamic visual simulation method was proposed for hydraulic and hydroelectric engineering, in which graphical modeling, dynamic simulation of the entire construction process and GIS-based visualization were realized. Graphical modeling facilitated the establishment of simulation model by combining graphic model elements based on hierarchical modular modeling theory. Entire progress dynamic simulation used ＂double simulation clocks＂ to simulate the entire process of construction, taking account of both integrity and detail. GIS-based three-dimensional visualization altered the presentation pattern of simulation result, which was a powerful tool for analyzing and management of construction process. The application to a real project verifies the feasibility of the methodology.
