Construction Diversion Planning of Super-high Arch Dam in the Middle and Later Stages

Combining the diversion project planning design with construction experience of super-high arch dam,the paper proposes that the super-high arch dam construction diversion period be divided into three stages,i.e.the early,middle and later stages by criteria,and especially gives the diversion design standards of middle and later stages,layout of flood prevention structure,selection methods and control elements of block,which provides an important reference for the design and construction of super-high arch dam.
