【摘要】 水电工程施工过程复杂,传统工程管理方法难以实现高效的管理。可视化仿真可以直观表现当前工程进度、方案,但实时建模比较困难。基于图形建模技术,在空间坐标描述基础上加入时间维,建立了含时间属性的层次性图形模型:单元模型、工序模型和场景模型;提出了水电工程施工过程可视化系统建模的方法。工程应用的表明,该建模方式对不同类型的水电工程有着较好的适用性。更多还原

【Abstract】 The construction of hydroelectric project is complicated. With traditional engineering management method, the decision maker is hard to be efficient. The visualization simulation can represent the construction scheme and schedule in real-time, however, the system modeling is hard. Based on the object-oriented graphics modeling technology, the graphics models sorted by hierarchy ---unit model, procedure model, scene model---were constructed in the four-dimensional coordinates which included the fourth dimension---time. The modeling method of visualization of hydroelectric project construction was proposed. And the application examples show that for different hydroelectric projects the modeling method has general applicability.更多还原
