在水电工程施工过程中,受施工组织、外部环境条件变化等因素影响,各种施工冲突、施工干扰问题时有发生,对工程施工质量、安全及进度等带来不同程度的影响,尤其是涉及大规模群体性建筑结构时,紧张的施工时段、有限的施工空间、多台套施工设备之间的关系更为复杂。由于缺乏有效的技术手段和技术工具,分析解决此类问题十分困难。为此,本文将时空碰撞检查概念引入水电工程施工,融合4D模拟和碰撞检查2项BIM功能,介绍了时空碰撞检查的研究方法、技术路线与实施步骤,应用于洞室群开挖、大型施工设备安装运行等工程实例中,对施工过程中可能产生的施工冲突问题提出了预警和解决方案,取得了理想的效果,为类似工程问题提供了研究思路和解决途径。

During hydropower project construction, various construction conflicts and interference pose different effects on the quality, safety and schedule of the project. In particular, the relations among period, space, and facilities of large-scale group construction are much more complicated. In order to analyze and solve these problems, we introduce the concept of space-time collision detection into hydropower engineering construction by integrating the 4D simulation and collision detection functions in BIM (Building Information Model), and propose the implementation methods and procedures of collision detection. We apply the space-time collision detection method to engineering projects like cavern group excavation and large-scale construction equipment installation and operation, and propose early warning and solutions to possible conflicts in the process of construction.
