Abstract:This paper analyses the bearing force characteristics of cylindrical caisson, compares the internal force and deformation of three types of cylindrical caissons based on a project example, and calculates the steel bars and the width of the crack, the results of which indicate that the internal force and deformation of cylindrical caissons without partition are the maximum, but in this project three types of cylindrical caissons all satisfy the requirements.It is recommended that in the design of cylindrical caissons, we shall take cylindrical caisson without partition into account firstly, and consider other types with partitions when it can’t satisfy the requirements.
