摘　　要：宝泉抽水蓄能电站上水库工程主坝上游面和库岸周边采用沥青混凝土面板防渗、库底采用黏土防渗,为了保证沥青混凝土面板和黏土的防渗质量,对原材料、沥青混凝土配合比和各种接头进行了大量试验研究,取得了最优方案,编制了各施工工序质量控制措施,严格控制施工质量,经过检验满足工程质量标准。在浆砌石副坝面板上涂刷聚腺后不渗漏,在没有反向渗透压力的情况下,涂刷聚豚的防渗效果很好。上水库已经过十年蓄水运行,通过监测数据分析,渗漏量远远小于设计指标,防渗效果良好。类似工程可以参考借鉴。In the upper reservoir project of Baoquan Pumped Storage Power Stati on,asphalt con Crete panels were adopted as antiseepage material of the main dam upstream face and the periphery of the reservoir bank,while clay was employed at the bottom of the reservoir to prevent seepage.In order to guarantee the anti-seepage performanee of the asphalt concrete panels and clay,the optimal scheme was obtained after a large number of experiments conducted on the raw materials,asphalt concrete mixture ratio,and various joints.The quality control measures for each construction process were drew up.The quality of construction was strictly controlled and the engineering quality stmndard was met after inspection.There is no leakage on the masonry secondary dam panels after spraying polyurea on them.Without reverse osmosis pressure,the anti-seepage performanee of brushing polyurea is perfect.The upper reservoir has been operating functionally for 10 years.Through the analysis of monitoring data,the leakage was far less than the design index,indicating a satisfied anti-seepage performanee,which can be used as a referenee for similar projects.
