摘要
结合京沪高铁京杭运河特大桥工程,对悬臂浇筑梁线形控制技术进行了探讨,详细介绍了平面与高程控制、支架及挂篮挠度控制、梁体线形预测及监控、基础沉降变形观测、梁顶六面坡控制等线形控制综合技术。
Combined with the Grand Canal Bridge of the Beijing-Shanghai High-speed Railway, the linear control tech- niques of continuous cantilever beam pouting are discussed in this paper. The techniques including plane and elevation con- trol, stent and hanging basket deflection control, prediction and monitoring of beam linearity, observation of base settlement and deformation, and six-planar slope control of beam top are all introduced in details.
