The Design And Calculation Of Fushun Wanxin Bridge And Research On Anchor Span

Fushun Wanxin Bridge is a Self-anchored Concrete Suspension Bridge. A new anchoring method is put forward because the riverbed of Hunhe River is shallow and the flood water level is high. Main cable enlaces the anchor, so the size of the anchor is reduced as small as possible. This anchoring method is first adopted in civil self-anchored suspension bridge. Consulting some references about the Self-Anchored Suspension Bridge in this paper, summing up the characteristics of them and sorting the anchoring method.Confirming the final cable force of the Self-Anchored Suspension Bridge is an important content of the structural calculation, however the key of confirming the final cable force is obtaining the shape of main cable. Utilizing continuous beam of rigid bearing to confirm initial sling force (reckoning in horizontal component force of main cable force. Using the software of Midas civil to calculate and obtain the shape of main cable. Creating the Finite Element Model in the software of Ansys and obtaining the ideal state of completed bridge, so the c able force i s the final c able force. B y calculating every working way, confirming the main cable force at the service-ability limit state.Using the software of Solidworks2000 to create the solid model of anchor span. By importing it into the software of Ansys, creating the finite element model of anchor span. By analyzing the stress distribution of anchor span at construction stage and working stage, the paper draws some valuable conclusions. And ome advice is proposed to improve the design. The stress distribution of the amendatory anchor span achieves design criterion. Moreover the method and conclusions are valuable for the design of the same type bridge.
