Comparison and Selectionof Dam Site and Dam Type and Structural Designof Dam Body in Heping Reservoir
The comparison and selection of dam type at the dam site is an important part of the reservoir hub design.The determination of dam site and the selection of dam type have a great impact on the project investment and quality safety.In view of the unfavorable geological problems such as strong karst strata in the dam section of Heping reservoir,which are prone to river bed leakage,and considering the reservoir forming conditions,water storage capacity,hydroproject layout,construction conditions and other factors,the lower dam site face rockfill dam is designed and optimized.The analysis shows that the lower dam site has strong water storage capacity and stable reservoir bank,which is conducive to the layout of CFRD hub.Although the amount of anti-seepage works is slightly larger than that of core wall dam,the suitability of CFRD dam type is strong,and the investment economic benefit is good.
