In this paper, a particular hydropower project ...... tubular arch hydroelectric project layout design optimization studies carried out . Bulb Turbine Hydropower use the universal law of the design , combined with arches hydropower engineering geological characteristics of the terrain , flood characteristics and plant operating characteristics, research and analysis of the original design in the project layout , each building coordination , spillway pier structure , energy dissipation erosion control and power station tailrace areas such as the lack of clearly pointed out in the original design problems in project layout . Through the general layout , crest layout, design and plant energy dissipation export layout design optimization and experimental research, to obtain compression overflow edge width 24m, shorten spillway bottom width 2.78m, reducing the length of spillway downstream apron 10 ~ 20m, spillway and power plant maintenance door intake trash rack hoist sharing such results. Hydroelectric power generation project has now archway , a project after a year of actual operation , confirming optimization studies to good effect.
