锦屏一级水电站库水位站建设方案研究与探讨

Discussion on construction scheme of reservoir stage gauging station of Jinping I Hydropower Station

针对锦屏一级水电站水库88 m的巨大水位变幅,着重考虑水库观测水位的代表性、可靠性和精确性要求,从库水位站的建设位置、建设形式、水位传感器比选等多个方面展开了详细的分析和探讨。经多方调研讨论,最终确定了一套地下两级竖井式测井结合地面一级塔式测井的库水位站建设方案。研究成果可供其他大型水库水位站的建设参考和借鉴。

In view of the huge reservoir water - level amplitude （88m） of Jinping I Hydropower Station, focusing on the repre- sentativeness, reliability and accuracy of reservoir＇s water- level observation, the related issues were analyzed and discussed in detail from the aspects of construction form, selection of construction location and stage sensor selection of reservoir stage gauging station. Finally, a construction scheme of reservoir stage gauging station with 2 underground shaft level logging and 1 surface tow- er level logging was formulated, which is adapt to the characteristics and requirements of Jinping I Hydropower Station and can be referred for similar projects.
