建设工程项目4D可视化动态管理系统的研究与开发

An Integrated Visualization System for 4D Construction Processes Simulation

综合应用了4D技术、虚拟现实技术、工程数据库,研究开发了建设工程项目4D可视化动态管理系统.该系统通过建立施工现场的3D可视化模型与工程相关资源的集成,形成了4D施工模型,实现了建设工程项目的进度、人力、材料、设备、成本和场地布置的4D动态集成管理,以及整个施工过程的4D可视化模拟,为工程管理人员提供了科学、有效的辅助管理手段,从而更有利于保质、按时、低耗地完成各项工程任务.

The integrated four dimension system provides an opportunity to improve an existing construction schedule by identifying inconsistencies and out-of sequence activities; reducing missing activities; and improving the ability to communicate construction plan information. The potential benefits and challenges of using an immersive, three dimension virtual environment to view four dimension models is investigated in the four dimension system and the use of an immersive virtual environment is also included, which aims to improve the project planning process by generating and reviewing construction plans in a virtual environment.
