Abstract:In order to protect people's life and property, the Guojiakou sluice was design for reinforcement and the design scheme was discussed. Considering current problems and the engineering scale and level, the design scheme was compared and selected under the aspect of sluice form, safety and reliability, construction investment, operation and management and project life. After hydrologic and hydraulic calculation of various forms of sluice, it’s determined whether the flood control standard and the requirement for supplying city landscape water was satisfied, and plane steel gate went as the optimal selection for Guojiakou sluice considering all perspective factors and multi-purpose development and utilization. This paper presents the Guojiakou sluice as an engineering example in which selection of multifunctional slucice design schemes was discussed , it can provide reference for similar sluice design.
