Cutterhead is one of the most critical components of shield machine.

刀盘是盾构机中极其重要的部件，本文介绍了盾构机刀盘液压控制的驱动系统、密封系统及自动润滑系统的工作原理及其维护方法。

Theoretical equations by analyzing earth pressure balance shield cutterhead′s cutting the ground are deduced and the numerical model is set up.

通过对土压平衡盾构掘进机刀盘切削土体进行理论分析，建立数学模型，得出相应计算公式。

The interaction between cutterhead of shield machine and soils was simulated. The investigation shows that there exists a wider range from active pressure to passive pressure for supporting face stability.

研究表明，仅从保证地表既不隆起又不沉陷的约束条件考虑，掘进工作面从主动土压力到被动土压力存在较大的范围。

The realistic face pressure is expected to be equal to earth pressure at-rest both for making face stability and decreasing fraction resistance between cutterhead of shield and soils during tunneling process.

考虑到减少刀具磨损和节约能源问题，推荐理想的掘进工作面土压力为静止侧向土压力。

Compared with the field measurements, the formula is suitable for the distance within the shield cutterhead (±2L), which can help guiding actual tunnel construction.

通过实例计算并与实测结果对比发现，使用盾构变形计算公式适用范围在盾构机头前后±2L距离处，对指导实际盾构施工具有重要意义。

As tunneling and cutting equipment of a shield machine ,the cutterhead can excavate stratum,stabilize excavation face,mix soil slag, etc.

刀盘是机械化盾构机的掘削机构，具有开挖地层、稳定开挖面、搅拌渣土等功能，并承受大扭矩、大推力和冲击载荷的作用，其工作状况非常恶劣。

Derived from Mindlin solution, the deformation formula induced by torque between cutterhead and soil is obtained by integration and coordinate transformation, which leads to the total deformation formula induced by shield tunneling.

基于盾构施工过程，利用弹性力学Mindlin解，通过坐标变换经积分推导刀盘与土体之间摩擦力所引起的地面变形计算公式，并得到盾构施工引起的总地面变形计算公式。
