基于BIM的混凝土重力坝浇筑方案自动规划系统开发研究

Research on Development of Automatic Planning System for Concrete Gravity Dam Pouring Scheme Base on BIM

针对目前混凝土重力坝浇筑方案采用人工规划时间成本大、成效低、调整复杂、方案直观程度低等问题,基于建筑信息模型(BIM)技术,利用Revit平台,开发了混凝土重力坝浇筑方案自动规划系统。该系统通过将浇筑信息与BIM模型关联,直接抓取大坝数字模型信息,具有计算浇筑相关参数、浇筑约束条件自定义、坝块排期、甘特图绘制、大坝节点面貌显示、模拟浇筑等功能。通过朱溪水库拦河坝的工程实例,验证了该系统的便捷性、高效性和直观性,同时亦为类似系统的开发研究提供了借鉴。

Manually planning concrete gravity dam pouring scheme is time consuming,lower efficiency and complex.It is also difficult to make adjustment and to visualize the process.An automatic BIM-based pouring scheme planning system is proposed.The system associates the pouring information with the BIM model directly,and is capable to do the pouring-related parameters calculation,pouring constraints customization,dam blocks scheduling,Gantt charts drawing,dam timeframe display,pouring process visualization.Finally,this paper uses the Zhuxi Dam as an example to verify the efficiency and intuitiveness of the system,which provides a reference for research on the development of similar systems.
