Research On Complex Guyed Traveler Construction Technique

In recent years, along with the economical development, the long-span bridge construction entered a new development phase. Both the long-spanning and the low cost is required. Cable-stayed bridge is a kind of bridge style of having lightness structure and large span capability, which develops quickly and steady in the past decades. One kind of pre-stressed concrete cable-stayed bridge which has inverse triangle main piers and single cable plane, has the structure of lightly,beauty of linear. Compared with the steel structure, it has the low cost in construction and good social efficiency and the economic efficiency, has been growing up rapidly in the recent years.The main pier construction is very difficult, because the stability of normal Guyed Traveler is bad in moving .Developing a kind of construction technology to adapt to this cable-stayed bridge, make a great progress in cantilever construction of a cable-stayed bridge and can promote the development of this type of cable-stayed bridge, which will play a great role in the construction of the same bridge in the future.Complex Guyed Traveler is adopted in the bridge completely and it combines the middle supporting basket and guyed basket. Based on GaoZan cable-stayed bridge construction craft, this paper simulates and analysis the construction state of GaoZan cable-stayed bridge, calculate the construction process each stage main piers deflection change and cable force and main piers stress ,and so on. Has drawn some useful conclusions, with will instruct the construction of same type bridge in the future..
