基于GIS的混凝土坝施工三维动态可视化仿真研究

为简化水电工程混凝土坝施工仿真的建模，同时实现施工过程中复杂动态时空逻辑关系的直观表达，提出了基于GIS的混凝土坝施工三维动态可视化仿真方法。通过计算分析不同方案下大坝施工的具体技术指标，可得到合理的大坝混凝土浇筑进度计划，并应用GIS技术在建立的混凝土坝施工系统数字模型基础上，用三维动态演示技术将复杂的大坝施工过程用运动着的画面形象逼真地描绘出来，从而为工程施工组织设计与管理提供了强有力的可视化分析手段。

GIS-Based Three-Dimension Dynamic Visual Simulation for Concrete Dam Construction Process

To simplify the simulation modeling for the concrete dam construction process of the hydroelectric engineering, and realize the visualization of the complex dynamic space|time relationship among construction works, this paper presents a new method called GIS|based three|dimension dynamic visual simulation for concrete dam construction process. After being calculated and analyzed the dam construction parameters under different construction conditions respectively, the reasonable construction schedule is obtained. And based on the digital model of the concrete dam construction system, which is created with GIS technique, the three|dimension process of dam construction is displayed dynamically. The approach described in the paper provides a powerful visually analyzing tool for the design and organization of dam construction.
