A detailed test on tunnel machine excavation parameter was given, and then the relationship between cutter head torque and tools wear under different underground conditions was analyzed. Some measures for shield posture control and a brief introduction on synchronized grouting parameters and slurry cycle system were also given. In the end, a conclusion on the importance of excavation parameter and slurry density in machine excavation was made.
