Abstract
A thorough study was made on the layout of the hydraulic structure complex ,the flood dischar-ging and the energy dissipation and the construction diversion of the Manwan hydropower project in its de-sign stage .The proposals concerning the design of the hydraulic structure complex were presented ,which tally with the natural conditions of the damsite area .Their essential is “make best use of the advantages and bypass the disadvantages” ,i .e .to give full play to the favorable topographical and geological advanta-ges of the right bank and its alluvial plain and to solve the auxiliary flood discharging and construction di-version problems ;to avoid the unfavorable topographical and geological disadvantages of the left bank , where no discharge structure should be placed .Their distinguishing feature is that all the structures are mutually coordinated ,both flood discharge and energy dissipation are safe and reliable ,the open channel is just suited to the construction diversion ,the solution of the inflow quality control problem of the power in-take is desirable ,the advanced technology at home related to the construction of the project can be em-ployed as much as possible ,the technical and economic indexes are superior ,w hich obtained the approval of both the ministry and the experts of the design institute .But the pity is that the proposals were not ac-cepted for a variety of reasons .T he practice has proved that if the proposals had been accepted ,the land-slide that occurred three times in the early construction stage of the project ,the delay of the construction schedule and the huge investment loss caused by the landslide would have been avoided .30 years passed , the review of where the value of the proposals being at is worth the related colleagues’ while to draw les-sons .关键词
