The ship lift of Three Gorges Project is huge and technically complex, and as there is no similar ship lift in the world as a precedent putting into operation, it has been well concerned by domestic and international engineering and technical community. The design and research process of Three Gorges Project ship lift , has been strongly supported by many domestic scientific research and design units, their works provide a theoretical basis for the gradual improvement of the ship lift design. After scheme comparison, the Three Gorges Project ship lift eventually identified as rack and pinion climbing type, its equipment is of complex structure and its manufacture, installation and civil structure need high construction precision requirements, and the Sino-German joint design approach is adopted for the first time. The final review and acceptance for the design results of every stages are executed by Quality Experts Group of Three Gorges Project organized by the Three Gorges Project Corporation. For the technical difficulties and key technical issues of the ship lift, a series of special experimental researchs, such as "research on manufacturing technology of rack, nut column" are organized to examine the rationality and implement ability of the key project design of ship lift .To reduce the effect of tower column deformation on the installation accuracy of rack and nut column, some research and adjustment are done to the construction procedures of ship lift to ensure safe and reliable operation of ship lift. Engineering construction proofs that the management, technical measures undertaken in this paper are scientific and they ensure the smooth implementation of the construction of the Three Gorges Project ship lift.
