摘要
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 4 D 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.
