Step (3.5.6): Sliding Structures internal force and The deformation calculation and control module make the following judgment: Sliding Structures internal force and The deformation calculation and control module are judged structure whether in elastic range according to internal force, and check structural strength and stability; Sliding Structures internal force and The deformation calculation and control module judge whether bumped with surrounding structure by Sliding Structures according to deformation state; If structural strength, stability and distortion situation all meet the demands, slippage is proceeded; If structural strength, stability or distortion situation occur unusual, Sliding Structures internal force and The deformation calculation and control module can in time give the alarm, and the slippage of time-out structure during situation danger is proceeded after waiting to reformulate scheme;
Step (3.6): treat completing steps (3.3), the creep setpoint position-measurement device reads the actual displacement value h of each creep setpoint in the 1st grade of slippage 1j (1), it is fed back to Sliding Structures key point displacement synchronization control module;
Step (3.7): Sliding Structures key point displacement synchronization control module receives the data that the creep setpoint position-measurement device transmits, and comprises the shift value h of the actual generation of each creep setpoint 1j (1)By contrasting each creep setpoint actual position value h 1j (1)With target location h 1j, calculate slip locations error delta h 1j (1)=h 1j-h 1j (1)
Step (3.8): Sliding Structures key point displacement synchronization control module makes the following judgment: if | Δ h 1j (1)/ h 1j|≤e all satisfies each j, enters step (4); Otherwise, be calculated as the oil pressure Δ that remedies the required adjustment of each creep setpoint place boosting facility of this error 1j (1), with Δ 1j (1)Be transferred to boosting facility oil pressure control and adjusting module;
Step (3.9): in boosting facility oil pressure control and adjusting module, with Δ 1j (1)Be foundation, change the boosting facility oil pressure at each creep setpoint place, carry out the fine setting of the position of creep setpoint; Meanwhile, repeating step (3.5) carries out the internal force and the deformation Check of Sliding Structures;
Step (3.10): treat that creep setpoint finishes this time fine setting, read the actual displacement value h of each creep setpoint in the 1st grade of slippage that the creep setpoint position-measurement device obtains 1j (2), repeating step (3.7)～step (3.10) repeatedly afterwards, after adjusting creep setpoint the k time | Δ h 1j (k+1)/ h 1j|≤e all satisfies each j, enters step (4);
Step (4): carry out the 2nd grade and follow-up slippage, repeating step (3) slides onto the target location until each creep setpoint.
