摘要
回顾敦化抽水蓄能电站前期工程地质勘察工作,梳理分析输水发电系统的勘察重点,主要包括:地下厂房位置及轴线的选择、地下厂房洞室群围岩稳定分析、地应力与岩爆评价、高压管道和岔管段围岩渗透特性研究、高压管道衬砌形式选择等。
The investigation emphases on water conveyance and power generation system of Dunhua pumped storage power station are analyzed through reviewing the preliminary engineering geological investigation, which mainly including the selection of location and axis of the underground powerhouse, the stability analysis of surrounding rock of underground powerhouse cavern complex, the evaluation of ground stress and rock burst, the seepage characteristics for the surrounding rock of high pressure pipes and branch pipe sections, and the selection of lining pattern of high pressure pipeline.
