To improve the adaptability of singleshield
TBM in longdistance hard rock formation, two systems
are designed to prevent and rectify the roll of singleshield
TBM in tunneling. Based on the analysis of the causes and influencing factors
of the roll of singleshield TBM, two kinds of shield
TBM roll rectifying techniques for singleshield TBM
with oneway mucking are proposed, namely, the shield
active roll rectifying technology without segment dependence and roll
rectifying technology through thrust cylinder deflection. The connection
between the two kinds of shield roll rectifying techniques is explained, a
mathematical model for shield body attitude control is established, the
critical conditions of shield body rolling and the requirements to be met for
controlling the shield body attitude are expounded, and the feasibility and
effectiveness of controlling the shield body attitude by thrust cylinder
deflection is illustrated with an engineering example.
