摘要
为保证192 m超高墩芦沟河特大桥的顺利施工,将BIM技术及整体式高效施工平台运用于芦沟河特大桥左幅7号高墩的施工阶段。先通过Revit软件进行精细化建模,再导入Navisworks软件中进行施工方案设计与动画模拟。研究结果表明,经碰撞检测及内部三维分析后发现问题2处,对其改进后运用于实际施工中,提前85 d完成192 m超高墩封顶。另外,Revit软件可实现快速建模,但在实际工程中运用BIM技术时应结合详细的地勘资料,才能保证设计、施工方案的准确性。经原有造塔机局部优化后的整体式高效施工平台可运用于超高墩大跨径连续刚构桥施工阶段,在一定程度上能加快施工进度。研究成果可为超高墩大跨径连续刚构桥的施工过程提供实际经验,保障施工的顺利进行。
In order to ensure the smooth construction of Lugou River Super Large Bridge with 192 m super high pier,BIM technology and integrated high-efficiency construction platform are applied to the construction stage of No.7 high pier on the left side of Lugou River Super Major Bridge.Firstly,fine modeling is carried out through Revit software.Then,Navisworks software is imported for construction scheme design and animation simulation.The research results show that two problems were found after collision detection and internal three-dimensional analysis.After improvement,it was used in actual construction,and the 192 m super high pier was capped 85 days in advance.In addition,Revit software can realize rapid modeling,but when BIM technology is used in actual projects,it should be combined with detailed geological exploration data to ensure the accuracy of design and construction scheme.The integral high-efficiency construction platform after local optimization of the original tower crane can be applied to the construction stage of the super-high pier long-span continuous rigid frame bridge,which can accelerate the construction progress to a certain extent.The research results can provide practical experience for the construction process of super-high pier long-span continuous rigid frame bridge and ensure the smooth construction.
