Background technology
Suspension bridge, has another name called suspension bridge (suspensionbridge), refers to cable (or steel chain) to be hung and to be anchored in two sides (or bridge two ends) by the Sarasota bridge as the main supporting member of superstructure. Its cable geometry, by equilibrium of forces conditional decision, generally approaches parabola. From cable many suspension rods that hang down, bridge floor is hung, between bridge floor and suspension rod, the standing stiff girder of putting, forms combined system with cable, to reduce the caused deflection deformation of mobile load.
Suspension bridge is mainly made up of parts such as suspension cable, Sarasota, anchorage, suspension rod, bridge decks. The main supporting member of suspension bridge is suspension cable, and its main bearing tension generally uses the steel that tensile strength is high (steel wire, wirerope etc.) to make. Generally in the both sides of bridge, one cables is set respectively, two ends are fixed on the anchor ingot of bank, bear weight by these two main push-towing ropes, two towering Sarasotas that keep at a certain distance away are set on river surface, for supporting main push-towing rope. Between two Sarasotas, be generally referred to as main span, two Sarasotas are generally referred to as end bay to the distance on bank.
Cat road is erected under main push-towing rope while being suspension bridge construction, be parallel to the linear temporary construction sidewalk of main push-towing rope. It is the height scaffolding that workmen carries out construction operation, is the operation platform of main push-towing rope system and even the whole superstructure of suspension bridge.
