斜拉桥施工监控技术的研究

Study on the Technology of Construction Control in Cable-stayed Bridge

在总结前人对斜拉桥施工控制经验的基础上,针对岔河大桥施工控制提出了相应的控制原则和方法,即以结构几何变形、应变以及索力作为三大监控指标,以"二次张拉"拉索为索力控制的方法,并根据各施工阶段的具体需要提出相应的施工监控方案。

on the base of generalization of the old experiences of construction control of the cable-stayed bridge,the construction control principle and method was put forward according the Chahe Bridge,that is take deformation, strain and cable tension as the measuring of ＂Three factors＂,take＂two times stretch＂for cable as control method of cable force and design corresponding construction procedure according to the specific requirements of each construction stage.
