Automatic tunneling method of shield tunneling machine

The invention discloses an automatic tunneling method of a shield tunneling machine, which comprises the following steps: S01, starting the shield tunneling machine, and manually setting parameter values of a soil bin pressure automatic dynamic balance module, a posture automatic deviation correction module, a muck automatic improvement module and a shield tail grease automatic injection module of the shield tunneling machine; s02, a one-key start-stop key is pressed down, a propelling system, a screw conveyor system, a foam system, a cutterhead system, a shield tail grease system, a gear oil system, a grease system and a water system are started, and tunneling is started; and S03, real-time data in the tunneling process of the shield tunneling machine are obtained through a soil bin pressure automatic dynamic balance module, an attitude automatic deviation correction module, a muck automatic improvement module and a shield tail grease automatic injection module, and automatic adjustment of the shield tunneli
