According to current characteristics of navigation of the Yongjiang waterway and along the port, this paper analyzes the shipping status and development of Yongjiang river waterway systematically. On this basis, controlling elements of the research on sluices are studied through waterway status, and the impact on the regional shipping of the sluices is studied comprehensively and deeply. 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.
