基于GIS和面向对象方法的大坝施工可视化仿真

Visual simulation based upon GIS of dam construction

基于G IS技术和面向对象方法,提出了一种新的对大坝施工进行可视化仿真的方法.综合运用G IS软件、AutoCAD和VC++软件,应用全新的仿真系统框架和运行机理,开发了相应的大坝施工可视化软件,并结合景洪水电站混凝土坝工程的施工仿真进行了实例研究.实践证明,这种仿真方法不但可以提高施工仿真的精度和可信度,而且可以呈现复杂施工过程中各施工单元的时间、空间和逻辑关系,揭示施工系统的动态行为特征,使复杂的仿真过程以一种更为直观的方式表现出来.

Based on the technique of GIS and object - orient method, put forward a new kind of visual simulation method for dam construction. Using the GIS and AutoCAD software as well as VC ＋ ＋ software, developed corresponding emluator about dam construction and studied the application of this method in the construction of Jinghong concrete dam. It was proved in practice that this new method mentioned above can not only improve the precision and the reliability of the visual simulation, but also express the relationship which is composed of time, space and logic factors between each sections of the construction and display the dynamic behavior characters of the construction system. What＇ s more, it makes the complex procedure of simulation vivid and simple to understand, which throw new light on the study upon visual simulation of large - scale civil engineering.
