The maximum navigable head of Baise hydropower station is 113.80 m.The water level of the upstream reservoir varies greatly，while the water level of the downstream Youjiang changes rapidly.The construction of navigation facilities is faced with such technical problems as navigation at high water head，saving water resources and reducing the influence on the safety and operation of the built facilities.The construction scheme should achieve the optimal coordination effect of multiple objectives，such as high-efficient navigation，reliable operation，convenient maintenance and economic investment.For the navigation facilities of Baise hydropower station，the combination of lock and ship lift，ship lift and ship lift，single-stage ship lift and multi-stage ship lock are adopted for technical and economic comparison.The combination scheme of ship lock and ship lift is recommended，which gives full play to the technical advantages of ship lock adaptation to large water level amplitude variation，large lifting height of ship lock and short time for ship lock passage.We compare and select the types of ship lift.The proposed combination scheme of ship lock and fully balanced vertical ship lift can achieve the construction objectives of efficient navigation and reliable operation.This paper puts forward a new idea for realizing high dam navigation，which has positive reference significance for the construction of similar projects and the revision of codes.
