| 摘 要： | 以最小二乘法为基础,提出了自锚式悬索桥施工过程中的非线性误差调整方法。研究表明,对于索力误差,可以通过部分吊索索力的调整得以消除;而对于主梁和索塔的变形误差,则需要进行全桥吊索索力的调整加以消除,以获得令人满意的吊索索力误差。

| Abstract: | Based on the least squares method,the method of nonlinear error adjustment of selfanchored suspension bridge in construction is presented.The study shows that the cable force errors can be eliminated through adjusting part of the cable force.Deformation errors of the main girder and the cable tower should be eliminated through adjusting the cable force of all hangers,to get the satisfied force errors. |
