摘要： PROBLEM TO BE SOLVED: To perform excavation direction control of a shield machine by obtaining necessary total thrust and bending moment from propulsion jacks in operation in a simultaneous excavation/assembling method.SOLUTION: When a group of propulsion jacks (J9 to J12) corresponding to segment assembling positions is disabled while remaining propulsion jacks are operated, the central positions of J9 to J12 are expressed by an axis line angle θ2, J1 to J16 are divided into two groups A2, B2 which are separated by an axis line AX2 corresponding to the axis line angle θ2 into both sides, and first thrust distributions LA2, LB2 having gradients inclined in the direction of the axis line AX2 are set for the respective groups. The gradient ratio of the thrust distribution is determined by axial direction strength r2. A thrust sharing ratio Qi' of each propulsion jack is calculated according to the thrust distribution and changed by using deviation coefficients α, αto calculate a thrust sharing ratio Qi. A first target value TQi of each propulsion jack is set on the basis of the thrust sharing ratio Qi and target total thrust.

解决方案：当在一些剩余的推进千斤顶运行时，当一组对应于段组装位置的推进千斤顶（J9至J12）被禁用时，J9至J12的中心位置由轴线角度θ2表示，J1至J16为被分成由两轴对应于轴线角度θ2的轴线AX2分开的两组A2，B2，并且对于各组设定具有在轴线AX2的方向上倾斜的梯度的第一推力分布LA2，LB2 。推力分布的梯度比由轴向强度r2确定。每个推进千斤顶的推力分配比Qi'根据推力分布计算，并通过使用偏差系数α A ，α B < SB>计算推力分配比Qi。每个推进千斤顶的第一目标值TQi基于推力分配比率Qi和目标总推力来设定。版权所有（C）2013，JPO＆INPIT
