In the construction of a pneumatic caisson, the effect on surrounding structures is always an issue.The authors have developed a particle / element mixing method, which is a dynamic analysis method that has excellent deformation performance and is a dynamic analysis method, in order to predict the amount of ground deformation accompanying the pneumatic caisson construction process, and examines its applicability. In this paper, we extend the method we are working on and apply the particle / element mixture method to the effect prediction analysis of circular caisson. In the following, the impact analysis using the particle method for the erection of circular pneumatic caisson is reported.
