Beschreibung
Zusammenfassung:	A method for manufacturing prefabricated parallel steel wire preformed cable strands for a main cable of a suspension bridge, comprising: prefabricating a plurality of zinc-coated steel wires into cable strands in factory, wherein this step mainly comprises the fabrication and configuration of marked steel wires and standard steel wires and a steel wire placement and shaping procedure; preforming desired cross sections at positions of the cable strands corresponding to tower and splay saddles, in order to install the cable strands to the saddles. Both ends of each cable strand are anchored using hot-cast anchors, and then the cable strands are coiled and transported to the construction site, and then are mounted one by one. Due to high precision during fabrication, the cable strands have stable quality and can be quickly mounted.
