摘要
为了控制盾构机按照隧道设计轴线掘进,当盾构机实际位置与设计轴线偏差过大时,需要进行纠偏。为防止纠偏过度产生蛇形掘进,就要设计最优的纠偏曲线。对纠偏曲线设计的约束条件进行分析,通过推导建立了纠偏曲线模型。
To ensure the shield machine tunnel along the axis of the tunnel design,when the actual location and design of the shield machine axis deviation goes too large and needs to be corrected,it is necessary to design the optimal corrective curve to prevent overcorrection tunnel.This article analyzes corrective curve design constraints and establishes corrective curve model by derivation.It provides a reference for the correction curve design of the shield machine.
