| 摘 要： | 在施工中由于多种因素影响，斜拉桥的应力与变形的关系极为复杂。结合荷麻溪特大桥主朴的监控，建立了施工控制的计算模型，计算分析了自重、挂篮和施工荷载、斜拉索张力、收缩徐变对斜拉桥施工挠度的影响，确保了大桥顺利合拢及成桥线形顺畅准确。控制结果与实测比较吻合良好。

| Abstract: | Owing to the fact that there are quite a few influential factors existing in the construction of a cable-stayed bridge,the relationship between the stresses and deformation of it is extremely complex.With the monitoring and control of the main bridge of the Hemaxi Mega Bridge as a practical example,a construction-controlling calculation model is established in the paper,with the effects of its self-weight,the hanging basket,construction loads,the stretching force of the cable-stayed cables,and shrinkage cre... |
