This paper analyzes the cause of ladder-shaped bending of the high pressure rotor of No.6 210 MW generating unit in a power plant.The ladder-shaped bending of rotor happened during its starting stage due to rub and impact between rotor and static parts.It is found that the water in the interlayer of high pressure cylinder leads to cylinder's deforming and principal-axi' bending
resulting in the bending of rotor.The field processing of the rotor bending is introduced to provide a practicable approach.
