| 摘 要： | 斜拉桥是一种经济、合理、美观的桥型 ,目前大跨度斜拉桥的建设在我国方兴未艾。针对斜拉桥施工中的线型、内力等施工误差 ,推导了用最小二乘法对其进行调整的基本方程 ,提出了考虑结构几何非线性的误差调整方法。结合南京长江第二大桥南汊斜拉桥某一施工阶段的误差 ,给出了其具体应用方法。

| Abstract: | Cable-stayed bridge is a kind of bridge structure which is rational, economical and esthetic. The construction of long-span cable-stayed bridge is a recent tendency in our country now. To improve the construction error of long-span cable-stayed bridge, such as configuration, internal force, the basic equations of error adjustment are deduced, using the least square method. And the construction error adjustment methods are put forward, considering the geometric non-linearity of structure. Finally the least square method is used to adjust the construction error of Nanjing Second Yangtze River Bridge. |
