sinking wells

Hi，

The main difference between the circular precast segmental sinking wells and the shield tunnel is that the segment of the wells will move downward and the segment of the lining will stay at a certain place of the tunnel.

Therefore, I have a problem. If the first ring segment of the sinking wells is also equipped with a cross beam system composed of solid elements ( only the first ring segment ), in order to simulate the sinking process of the sinking wells ( assuming that there are 10 rings in total and the distance of each sinking is the height of one ring ), do I need to set this cross beam system at each ring, and then when my first ring passes, soil excavation is performed and the cross beam system pre-set there is activated. Then repeat the above steps and deactivate the crossbeam system activated in the previous step. Is it reasonable to do so?

Could you help me? Thank you
