摘　　要：过去二十年来,国内水电大规模快速开发利用,各主要河流规划的优良梯级资源基本开发殆尽,余下待开发的梯级大多存在自然条件不好、投资指标较差或受制于环保政策三方面因素的影响,大渡河干流东源自上而下的第2级电站-巴拉水电站就是典型的代表,其前期开发准备和立项过程同样因三方面的因素几经周折。在主体工程开工前近12年时间里,针对电站枢纽总布置格局持续性地、全方位地从技术经济角度开展了大量的优化研究工作,最后有效克服了内外影响因素带来的困难而核准实施。作为后水电开发时期的经典工程,针对巴拉水电站开发所遇到的内外困难,本文对巴拉电站枢纽布置格局调整过程中的几项核心技术进行梳理和研究,阐明枢纽布置格局技术优化对水电站开发的重要意义,给后水电时期开发有益启发。In the past two decades,domestic hydropower has been developed and utilized rapidly on a large scale and the cascade resources with high quality in major rivers have been basically exhausted.Most of the remaining cascades to be developed are observed with poor natural conditions,poor investment indices or are restricted by environment policies.Bala Hydropower Project,the second cascade of the east origin of Dadu River,is a typical example.Its early preparation process and approval process were though and encountered with all the mentioned 3 difficulties.In the past 12 years before the start of the main project,a large number of researched and optimizations on the general project layout were carried out continuously and comprehensively from a technical and economic perspective.Finally,the difficulties caused by internal and external factors were effectively overcome and the project was approved.As a classic project in the post-hydropower development period,in view of the internal and external difficulties encountered,this article sorts out and studies several key technologies in the process of adjusting the general layout of Bala Hydropower Project,and clarifies the importance of layout optimization on a hydropower project,which could provide useful inspiration for hydropower development in the post-hydropower period.
