Abstract: Based on the theory of elastic thin plate, semi-analytic method is applied to study the interaction among raft, up-structure and ground by considering the horizontal outer flexure and longitudinal plane total bend of underground construction sidewall. Comparing with the computational and field measured results without taking the effect of the sidewall, shows it is more practical for considering the horizontal outer flexure and longitudinal plane total bend. Based on the above study, the effect of sidewall stiffness on the forces acted on raft is analyzed; and the situation by changing the raft size is also discussed.

Key words: raft, interaction, deformation compatibility
