| 摘 要： | 部分斜拉桥受力和普通斜拉桥不完全一样,因而其施工控制具有自身的特点。以龟韭沟大桥为例,从结构尺寸和受力特点出发,结合实际施工控制方法和成果,从线形控制、应力控制和索力控制3方面,探讨了部分斜拉桥施工控制的特点,提出了相应的注意事项及解决方法。

Discussions on Characteristics of Construction Control for Extra-dosed Partially Cable-stayed Bridges |
| |
| Abstract: | Extra-dosed partially cable-stayed bridges are different from common cable-stayed bridges in stress control so that they have their own characteristics of construction control. Take Guijiugou Bridge as an example,we discussed the characteristics of construction control for extra-dosed partially cable-stayed bridges in terms of three aspects: geometry control, stress control and cable-tension control. We presented some possible problems and also proposed the solutions regarding to structure size and stress characteristics as well as the method for the practical construction control. |
