| Abstract: | The Xiaolangdi Multipurpose Dam Project is an extraordinary control project on the YellowRiver. The three free-flow tunnels are the major flood discharge works. This paper discusses thedesign concepts, characteristics and the results from several aspects. Contents are basic materials. design principles and requirements, structural layout and the determination of the structuretype, hydraulic design and hydraulic model testing, design of cavitation-reduction and abrasive resisancet. design of rock support. This paper also analyzes the key technical problems need to bestudied. Methods for solving these problems are proposed. |
