【 摘 要 】

Due to the breaking force of Φ14-1770, the three pre-tensioning process was designed and the wire rope was pre-tensioned. The result shows that the wire rope has different degrees of elongation and the elastic modulus increases by 60% breaking force pre-tension test. However, there is no change in the diameter of steel wire, indicating that the steel wire has no plastic deformation. The wire rope has different degrees of elongation, and the elastic modulus decreases by 80% breaking tension pretension test, indicating that the steel wire produces plastic deformation.
