Abstract: This paper briefly analyses settlement and horizontal deformation of the foundation rock at chamber head of the ship-lift during upper structure construction, also analyses the basic data about the open joint of the slit in the foundation slope section. The preliminary analysis indicates that the deformation of the foundation rock is reasonable, the open joint of the slit in the foundation slope section tends to be stable,the variation in one year is below 0.3 mm, it adheres to the normal roles of temperature deformation in mass concrete, and it adheres to the design requirements, the building’s safety condition is normal at present.
