惠州抽水蓄能电站地下厂房洞室群布置方案研究

Study on the Caverns Layout for Underground Powerhouse of Huizhou Pumped-Storage Power Station

惠州抽水蓄能电站前期设计工作中,对数量众多的地下厂房洞室群进行了多种组合布置方案的研究,优选后采用了厂房分区布置、其他附属洞室有分有合的布置形式;针对场区发育的控制性断层开展了综合研究,在查明断层的空间分布、性状的基础上,优化调整了地下厂房洞室群及高压隧洞位置。这些研究成果的实施,达到了地下厂房洞室群布置合理、建设灵活、节约投资的目的。

In the preliminary design of Huizhou Pumped-Storage Power Station, different combinations of a large number of underground caverns were studied, and two-powerhouse arrangement was selected after layout optimization. According to the field investigation, there is key fault in proposed arrangement area of caverns. The positions of underground caverns and pressure tunnels were adjusted according to the spatial distribution of the key fault. The adjustment of caverns arrangement will meet the requirements of reasonable layout, flexible excavation and minimum investment.
