摘　　要：宝泉抽水蓄能电站上水库主坝和库岸周边采用沥青混凝土面板防渗,库盆底部采用粘土铺盖防渗,接头部位形式复杂,施工难度较大。因此,工程接头部位的施工采用了国内的柔性滑动止水材料和特殊的止水结构形式。在施工中遇到了柔性滑动材料的粘结和楔形体填充材料等问题并得以解决。相信,这对以后类似工程会有实际的借鉴意义。The anti-seepages for the main dam and the surrounding bank-slope of the upper reservoir of Baoquan Pumped Stor- age Hydropower Station are made with the asphalt-concrete facings, while the anti-seepage for the bottom of the reservoir is made with clay blanket, thus the joint pattern between them is complicated with larger construction difficulty. Therefore, the domestic flexible-sliding water-stopping material and special water-stopping structures are adopted for the construction of the joint. During the construction, the problems from both the bonding of the flexible-sliding water-stopping material and the wed- ging filling material are encountered and solved. It is believed that it has reference significance for the similar projects in the days to come.
