摘要
抽水蓄能电站通常具备高水头与长输水线路的特点,其压力管道及岔管部分采用混凝土衬砌还是钢板衬砌,对整个工程的成本与建设周期有着显著的影响。本文探讨了某区域内的抽水蓄能电站中压力管道的衬砌形式选择问题。该工程中,压力管道在水平段及分流器区域的静水压力达到了740米的高度。考虑了岩石层的覆盖深度、岩石的物理特性、隧道的可能渗漏情况以及日常运营管理等因素,最终挑选出了最适合此工程的衬砌设计方案。
Pumped storage power stations usually feature high water heads and long water conveyance lines.Whether the concrete lining or steel plate lining is adopted for the penstocks and bifurcations has a significant impact on the cost and construction period of the entire project.This paper discusses the selection of the lining form for the penstocks in a pumped storage power station in a certain region.In this project,the hydrostatic pressure in the horizontal section and the diverter area of the penstocks reaches a height of 740 meters.Considering factors such as the overburden depth of the rock layer,the physical properties of the rock,the possible leakage of the tunnel and the daily operation and management,the lining design scheme most suitable for this project was finally selected.
