摘　　要：宁波常洪隧道江南暗埋段修建在管段制作的干坞范围内,其基底有需要垫高的,也有需要挖除干坞基础的。故设计的重点就是在满足结构的强度、刚度和稳定性后,减少不同结构段之间的不均匀沉降,使其变形控制在允许范围内。The cut and cover section at the south bank of Yongjiang River of Nigbo Chang Hong Tunnel is located in the dry dock for tunnel tube manufacturing. Some parts of the foundation need to be filled-up while some parts to be excavated. In design, emphasis is attached to the reduction of non-uniform settlement of different structure parts as to control the deformation in an allowable range on condition that the demand of the structural strength, rigidity and stability is fulfilled.
