周宁抽水蓄能电站上水库副坝坝型选择
发布时间:2018-08-28 08:55
【摘要】:福建周宁抽水蓄能电站上水库副坝坝址区具有垭口单薄、边坡陡、土质边坡稳定性差等特点,大坝布置条件较差,坝型选择具有一定的难度。可行性研究阶段,结合坝基和边坡的处理方案分别对土石坝方案和混凝土重力坝方案进行经济技术综合比选,最终选择施工风险低、运行安全可靠的重力坝方案。该工程副坝坝型选择的研究表明,对于抽水蓄能电站副坝,相比一般水电站或水库的大坝布置条件较为特殊,坝型选择时更要充分论证,综合考虑各种因素。
[Abstract]:The site of the auxiliary dam of Zhouning pumped Storage Power Station in Fujian Province is characterized by thin mouth, steep slope and poor stability of soil slope. The condition of dam layout is poor, and the selection of dam type is difficult. In the stage of feasibility study, combined with the treatment scheme of dam foundation and slope, the scheme of earth-rock dam and concrete gravity dam is compared and selected economically and technically respectively. Finally, the scheme of gravity dam with low construction risk and safe and reliable operation is selected. The study on the selection of dam type of auxiliary dam in this project shows that the conditions of dam layout of pumped-storage power station are more special than that of general hydropower station or reservoir, so the selection of dam type should be fully demonstrated and all kinds of factors should be considered comprehensively.
