| Abstract: | With the slurry shield, whose diameter is 14.93 m and which is used for the Nanjing Yangtze River Tunnel, as the object of study, suitable monitoring means are chosen, trouble-shooting schemes proposed and the yardsticks of some parameters in the key equipment given according to the faults that may occur in some main parts of the shield, such as the main bear, the large gear ring, the gear box, the main motor and the hydraulic system. The implementation of the condition-monitoring and trouble-shooting schemes helps ensure the smooth and efficient operation of the shield and provide a guarantee for the successful through-going of the tunnel. |
