| The construction of Concrete Filled with Steel Tubular(CFST) arch bridge has been developed in recent ten years in our country. Although about 40 bridges whose span are longer than 80 meters are constructed, there are only two through tiedæ¢rch bridges without wind bracing, including GuangZhou JieFang Bridge. It is well known that the integral hoisting construction method is firstly applied in this bridge. Then, a thorough discussion and sum梪p about the main construction process of CFST tiedæ¢rch bridge without wind bracing is presented in the paper in association with the construction practice of the bridge. In addition, the author put emphasis on the static calculation of two point integral hoisting construction method in single CFST arch rib. Futhermore, the stabilization of arch rib in construction and service stage are analyzed detailedly. So, corresponding suggestion is presented to assure the construction successfully according to the calculating results and some experience are got for the design and construction of this type arch bridge. |
