摘要：

介绍了曲线桥(半径R=1100m)T梁张拉和吊装过程中出现侧弯现象的控制和解决办法;对曲线桥T梁安装定位、架桥机过跨等技术,总结出一套曲线桥架设的施工工艺。

The paper introduces the control methods to the straining of the T-shaped beams for a curved bridge with a radius of R=1 100 m and the side bending of the beams during lifting and handling.A set of technology for building curved bridges is proposed after a summary is made of the techniques for positioning and installation of the T-shaped beams for curved bridges and the techniques for a bridge building machine to cross a bridge span.
