The original stress sate of the formation is destroyed in the shield tunneling construction. Formation stress increment, especially shear stress increment, will cause ground movement and result in ground settlement in different degree. If construction parameters are not in proper control in super large diameter slurry shield tunneling, too serious ground settlement will affect the safety and usage of ground construction. The summarization is made on a dyke-crossing construction project by large diameter slurry balance shield in Nanjing, which can be taken as reference to the similar construction.
