    ANALYSIS AND RESEARCH ON FORMATION CONDITIONS OF IMPOUNDING RESERVOIR FOR RONGGE HYDROPOWER STATION ON MENGJIANG RIVER

    • 摘要: 冗各水电站工程区岩相变化剧烈,沉积环境及地质构造背景复杂。库盆及水库左岸河间地块岩溶强烈发育,地下岩溶管道网络错综复杂,库尾见河水补给地下水,坝段上、下游有大型暗河出露及河床裂点分布,如此复杂的岩溶水文地质条件在国内实属少见。为分析论证水库成库条件,本次采用的大型示踪探测手段,利用经过抗吸附处理的分析纯萤光素作为示踪剂,野外大范围高频度昼夜监测,精密的F96C型荧光分光光度计进行分析检测,是国内首次获得定性定量分析成果用于水电建设的大型示踪探测项目,为示踪探测用于水利水电工程勘察提供了很好的实例。

       

      Abstract: The rock type is seriously various in the area of Rongge hydropower station, where the sedimentation environment and geological structure background are complicated. Karstification chips rock mass intensively around the reservoir and at the left bank of the reservoir, which results in a complicated net karst pipes under the ground. Also, there are some classic karst hydraulic phenomena in this area. For example, river recharges groundwater at the end of the reservoir; some large-scale underground rivers and fissures of the riverbed were found. To analyze conditions of the reservoir formation, large-scale tracer detector was employed to monitor frequently changes of tracer dose in water in a large scale day and night, where the tracer dose is a kind of fluorescein treated by anti-adsorption in advance. As for this detector, a precise spectral luminometer of fluorescein (F96C mode) is used to analyze the tracer dose. The detector is the first one that can obtain quantitative results for hydroelectric project. Also, the case study is a good reference for tracer detecting of the similar hydroelectric projects.
