摘要
永康市西塔桥为V形墩连续刚构桥,采用支架法现浇施工.通过对大跨度V形墩连续刚构桥挠度控制影响因素的分析,采用自适应方法进行施工控制,最后成功合龙桥梁.文中重点阐述了结构线形控制的实施控制过程,对同类桥梁的线形控制具有参考价值.
Xita Bridge in Yong Kang is a V-shape pier continuous rigid frame bridge which is constructed in the way of pouring trestle. As to long bridge of such type, there are several factors that influence the deflection control. With those factors analyzed, self-adaptive method is adopted for controlling. The course of the structure alignment control is elucidated primarily and some experiences are given for alignment control of this type of bridge.
