对盾构掘进参数进行了详细试验，对不同地层条件下刀盘扭矩与刀具磨损情况之间的关系进行了详细分析，并探讨了盾构姿态的控制方法，同时对同步注浆参数及泥水循环系统做以简要介绍，总结了掘进参数、泥浆密度等在盾构掘进中的重要地位。

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.
