Provided is a working method for a retractable ship-boarding trestle bridge with a function of position compensation. The working method comprises an overlap-joint method, a servo-compensation methodand a disengagement method. The overlap-joint method comprises a manual overlap-joint method and an active compensation overlap-joint method. The manual overlap-joint method is to control a handle such that the handle is controlled to send a signal to a control system. The control system controls a rotary hydraulic system, a retractable hydraulic system and an amplitude varying hydraulic system such that the retractable trestle bridge can move within the overlap-joint range. When the overlap-joint range is reached, the active compensation overlap-joint method is applied. Concretely speaking, asignal is detected through a sensor and a DP system. The control system controls the rotary hydraulic system, the retractable hydraulic system and the amplitude varying hydraulic system according tothe signal. Ultimately, overlap-joint is achieved. After overlap-joint is finished, the servo-compensation method is switched. With the working method, the trestle bridge is reliably, safely and efficiently overlapped. After overlap-joint is finished, servo movement of the retractable trestle bridge is achieved. Therefore, people and transport material can smoothly and stably pass. Meanwhile, loads applied to overlap-joint points are minimized.
