基于BIM的混凝土坝浇筑仿真智能建模方法研究
|
摘要
针对混凝土坝浇筑过程受自然环境、坝体结构、混凝土供应、坝体浇筑入仓手段等众多因素的影响,且各因素之间存在复杂的空间和时间的制约关系,使得目前混凝土坝浇筑仿真建模效率不高的问题,提出基于建筑信息模型(BIM)的混凝土坝浇筑仿真智能建模方法,以直接提取或间接转换的方式将BIM信息和混凝土坝浇筑仿真模型信息联系起来,实现一定程度上的智能建模。实例应用结果表明,该方法缩短了混凝土仿真模型构建时间,提高了模型构建效率和自动化程度,同时也使得建立的模型便于工程设计人员理解。
Concrete dam construction is affected by many factors,such as natural environment,the distinct structure of the concrete dam,concrete supply,dam pouring warehousing tools,etc.,and there is a complex relationship between space and time constraints of these factors,which makes the inefficiency of current concrete dam simulation modeling.For the above reasons,a intelligent modeling method of concrete dam pouring based BIM is proposed,which associates BIM and the simulation model information of concrete dam in the way of extracting directly or transformation indirectly,achieving a certain degree of intelligent modeling.The case study results show that this method can shorten the construction time of the simulation model of concrete dam and help improve efficiency and the degree of automation of model construction,but also make the model understood by the engineering staff easily.
