十三陵抽水蓄能电站地下厂房位置的选择

    LOCATING UNDERGROND POWER HOUSE FOR MING TOMBS PUMPING STORAGE STATION

    • 摘要: 十三陵抽水蓄能电站是以地下厂房为中心的大型水电工程。厂房位置的选取不论是在施工条件上,还是经济造价上,都是该工程最重要的问题之一。本文从厂房选取控制性因素厂区断裂特征的分析入手,依据各种物理力学指标对厂区洞室围岩进行了分类,同时分析评价了各种地质条件下的洞室围岩稳定性。最后对厂房3种布置方案的工程地质条件进行了分析对比,得出第三方案是本工程地下厂房最佳位置的结论。

       

      Abstract: The Ming Tombs Pumping Storage Power Station is a large scale hydropower projec t with an underground power house. Locating the power house is one of the mos t important problems for the project not only in the conditions for construction but also in economic cost. The paper analyses firstly the characteristics of f aults and fractures which control the location of the power house in the area. Secondly, the surrounding rocks of the power house is classified from some phys ical and mechanical indexes. Meanwhile, the stability of surrounding rocks of th e power house is analyzed and the different geological conditions are evaluated . Finally, the engineering geological conditions considered in three plans for locating the power house are compared. It follows that the plan Ⅲ is the best one.
