溧阳抽水蓄能电站地下厂房洞室群布置研究

Study on Cavern Layout for Underground Powerhouse of Liyang Pumped-storage Power Station

针对溧阳抽水蓄能电站厂区工程地质条件,对溧阳地下厂房洞室群的布置进行深入研究,重点对地下厂房的位置、纵轴线方向及球阀布置的选择等进行详细的论证。在此基础上介绍整个地下厂房洞室群的各主要建筑物的布置情况。目前施工和开挖揭露的厂区地质情况与前期勘探情况基本一致,进一步证实了电站地下厂房洞室群布置方案是合理的、可行的。

Based on engineering geological conditions of Liyang Pumped-storage Power Station, the cavern layout of underground powerhouse is studied in detaic, in which, the location and longitudinal axis direction of underground powerhouse and the ball valve layout are specially argued. The layout of other main structures in underground caverns is also introduced herein. The geological conditions revealed by current construction and excavation are basically consistent with investigation results, and this further confirms that the layout scheme of underground caverns is reasonable and feasible.
