Comparison and Selection of Dam Site and Dam Type for Lower Reservoir of Guilin Pumped Storage Power Station in Guangxi
The lower reservoir of Guilin Pumped Storage Power Station is located in a relatively symmetrical V-shaped canyon section,with strong mountains on both sides.From the perspective of topography,the lower reservoir has the conditions to build concrete dams and local material dams.The authors conduct a comparative study on the dam site and dam type of the lower reservoir dam from the aspects of topographic and geological conditions,construction conditions and engineering investment.By comparing the upper and lower dam sites with the dam type,the recommended dam type is determined,and the upper and lower dam sites are compared.Finally,the asphalt concrete core wall dam scheme of the lower reservoir dam site is selected.The research results can provide reference for the comparison and selection of dam site and dam type of similar projects.
