摘要
互通立交匝道桥部分形式多样,存在大量的弯道、斜坡道、分岔道及宽窄变道,桥面由多种曲线复合而成,其下部墩、台、桩等结构在施工平面位置坐标较难确定,施工测量难度大。以某互通工程为例,分析了各种施工测量控制点的计算方法,探讨了互通立交工程施工测量的关键,对实际工程匝道桥加密控制点的计算方法进行研究,取得了良好的效果,为施工测量的发展提供了方向,可供其他类似工程借鉴。
Interchange ramp bridge part is diverse.There are a large number of curves,ramps,diversions,and wide and narrow changes,bridge deck by a variety of compounded curves.Its lower pier,platform,pile and other structures in the construction plane position coordinates are difficult to be determined.Construction measurement is difficult.The study takes a interchange as an example,the study analyzes the calculation methods of various construction measurement control points,discusses the key points of construction measurement for interchange projects,and conducts an in-depth study on the calculation methods of encrypted control points for the actual project ramp bridges,achieves good results,and provides a direction for the future development of construction measurement,so as to provide reference for other similar projects.
