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.

Key words: construction control, characteristics, extra-dosed partically cable-stayed bridge

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。
