In shield tunneling process, shield-tunneling construction posture and Tunnel Design misalignment of axe size to ensure shield smoothly driving and
Pipe sheet assembling quality is most important.At this stage, shield driver is relied primarily on for the adjustment of the shield attitude in construction to rely on certainly
Oneself experience carries out override, and TBM's position control theory lacks, and far lags behind practice.Existing related research result is also difficult to answer
For Practical Project.Particularly, under high hydraulic condition, once there is relatively large deviation in shield attitude, that is, is in improper driving
Posture, rectifying a deviation to shield will become extremely difficult, and correction process disturbance stratum easily causes inwelling, excavation face unstability
Etc. major accidents.
When shield is tunneled in the earth formation, due to the hardness on stratum, the difference of coefficient of elasticity, it may occur however that pitching, sideway, torsion
Turn three kinds of movements, it is therefore desirable to which instant adjustment is carried out to the driving attitude of shield according to Tunnel Design axis.Shield pick is described
Into the current position of machine and posture, shield machine is needed to determine coordinate position and the pitch angle of shield body, yaw angle, the torsion of point
The parameters such as angle can be obtained the parameters information of shield machine driving attitude according to shield machine model assay system.According to monitoring
The situation of change for the stress index that system obtains, during being adjusted to shield attitude, the stress of shield machine is analyzed, into
And judge, the Mutual Influence Law of formation properties and shield excavation attitude.
