BIM技术在转体桥施工中的应用——以银西铁路跨定武高速公路转体桥为例

Application and research of BIM technology in construction of rotating bridge:Taking the rotating bridge of Yinxi railway across Dingwu expressway as an example

为了发掘BIM技术在桥梁施工中新的应用点,拓展其在桥梁施工中的建模功能,解决钢筋间的碰撞与冲突等问题,发挥其对施工现场的指导作用,以银西铁路跨定武高速公路立交连续梁工程为例,对全桥进行BIM技术建模,搭建施工管理平台,在施工现场应用BIM技术测量桥体变形,并对桥体进行定位,处理施工现场问题。得到了球铰的精确定位,实现了施工资料的上传、下载、保存以及对施工进度的实时监管操作,真正地将BIM技术应用于施工现场,体现了现场管控平台较强的时效性和操控性,确保了桥梁的顺利转体,保证了工程质量,拓展了BIM技术在施工现场中的应用,为同类施工现场管理提供参考。

In order to explore new application points of BIM technology and expand its modeling capability in bridge construction,also,to solve the problems such as collisions and conflicts between reinforcements,and then play its guiding role on the construction site.Based on the example of the construction of the continuous beam construction of the interchange of the cross Dingwu high speed in Yinxi railway. The application of BIM technology on measuring the bridge deformation and positioning at the construction site,as well as the the process of handling problems of construction site according to the on-site management platform. The application results not only obtained the precise positioning of the spherical hinge,but also realized the uploading,downloading and saving of the construction materials,realizing the real-time supervision operation on the construction progress,and truly applying the BIM technology to the construction site,reflecting the strong on-site management and control platform. Timeliness, convenient handling, ensuring the smooth transformation of the bridge,ensuring the quality of the project,expanding the application of BIM technology in the construction site,provide reference for the management of similar construction sites.
