浅谈箱梁悬臂施工平面及高程控制

Tentative discussion on surface and altitude control of box girder cantilever construction

通过建立施工测量网,探讨了箱梁悬臂施工平面及高程控制,分别介绍了基准点和梁段测点的埋设、箱梁悬浇施工控制测量、箱梁合龙监测、线形控制以及箱梁挠度变形处理等,保证了箱梁施工测量控制在设计要求范围内。

Through setting up construction measuring web,it explores the surface and altitude control of box girder cantilever construction,respectively introduces the burying of reference point and beam section measuring points,box girder pouring construction control measurement,box girder joints monitoring,linear control and box girder deflection deformation treatment and so on.As a result,it insures the box girder construction measurement is within the design requirement scope.
