This study investigated and analyzed the assembly attitude of prefabricated partition walls on the Shanghai Airport Link Line to ensure high assembly quality within largediameter shield tunnels. Initially, the coordinate system of the partition walls was established. Subsequently, the study examined the assembly attitude under initial assembly errors and errorfree scenarios. It focused on obtaining precise attitude information and the analytical expression of the partition wall's bottom plane equation for each operational condition. The analytical results reveal the following: 1) In scenarios where there are no initial assembly errors or where errors are limited to translation or rotation, the selection of control points and jacking sequences within the regulating system does not affect the assembly quality of the partition walls. The assembly attitude can be effectively managed using the derived expression for the wall's attitude. 2) When initial assembly errors extend beyond simple translation or rotation, precise control of the partition wall's attitude becomes crucial. This involves adjusting the jacking sequences within the regulating system accordingly. Utilizing the obtained expression allows for improved assembly accuracy of the partition walls. 3) The study successfully applied an analytical formula to constructing partition walls, demonstrating favorable engineering outcomes in practical applications.
