| Abstract: | The standards of load,stability and comfort are higher in quadruple-track high speed railway cable-stayed bridge than in ordinary railway bridges,which raise higher requirements of structure bearing capacity.After describing the analytical method of carrying capacity,this paper establish 3D finite element model with TDV-RmBridge professional software,and analyses the bearing capacity of a quadruple-track high speed railway cable-stayed truss bridge. |
