摘要
坝址坝型比选是水库枢纽设计的重要内容,坝址确定和坝型选取对工程投资和质量安全影响较大.针对和平水库建坝河段局部存在强岩溶地层,易产生河床渗漏等不利地质问题,综合考虑成库条件、蓄水能力、枢纽布置和施工条件等因素,设计优选下坝址面板堆石坝.论证分析表明:下坝址蓄水能力强且库岸稳定,利于面板堆石坝枢纽布置,虽防渗工程量较心墙坝略大,但面板坝坝型适宜性强,投资经济效益好.
Abstract
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.
