The distributing rule of additional forces of compressible shaft wall is given by numerical analysis and model test. It is shown that the compressible shaft wall can reduce the additional force and the section axial stress of shaft wall effectively; Compared to the single compressible tie-in

two compressible tie-ins setting is more effective. The setting optimization principle of compressible tie-in is brought forward; and it has important guidance meaning to design compressible shaft wall reasonably.
