摘要:

利用 Revit 软件和参数化建模思路,建立了某高速铁路节段预制全胶接拼装预应力混凝土梁预制阶段 BIM模型;利用 Navisworks 软件对节段梁各构件进行碰撞检查,提出设计阶段利用 BIM 模型对预应力管道和普通钢筋位置进行优化;基于预制阶段 BIM 模型,对预制阶段工程量进行统计,对模板配置提供帮助,可视化施工流程和管理施工人员、设备;利用 BIM 软件可对节段梁预制尺寸虚拟误差进行分析且提前进行处理,便于后续预制施工,辅助节段梁预制阶段的高精度尺寸和线形控制。

Using Revit software and parametric modeling ideas, a BIM model for the prefabrication stageof a high⁃speed railway segmental precast fully glued spliced prestressed concrete girder is established;Navisworks software is used to perform collision check on the various components of the segmental girder,and it is suggested that the BIM model is used in the design stage for optimization of the location ofprestressing pipelines and ordinary reinforcement; Based on the BIM model for prefabrication stage, itcan make statistics on the engineering quantity of prefabrication stage, provide help for formworkconfiguration,visualize the construction process, manage the construction personnel and equipments;BIM software can be used to analyze the virtual error of prefabrication size of segmental girders and dealwith it in advance,which is convenient for the subsequent prefabrication construction, and it can assist incontrolling the high⁃precision size and linear shape of the prefabrication stage of the segmental girders.
