斜拉桥塔梁同步施工中的索塔测量控制浅析

Construction of the Tower and Beam Synchronous Measurement and Control of cable-stayed Bridge Pylon

通过斜拉桥的塔梁同步施工状态下的索塔定位测量的研究分析,根据测量索塔已浇节段的变形值,模拟索塔的变形曲线,计算出索塔待浇节段的理论变形值,对模板和索导管的定位数据进行修正,使索塔线型和定位精度符合设计要求。

The tower cable-stayed bridge girder construction synchronization state Sarasota positioning measurement research and analysis, according to the measurement tower has been poured segment deformation, deformation curve simulation Sarasota, Sarasota calculated to be poured segment theoretical deformation of templates and positioning data cable conduit revised to make Sarasota linear positioning accuracy and meet the design requirements.
