摘要
酉酬水电站库区地貌单元多以岩溶地貌为主,通过对河湾地块岩溶地质问题的分析,采用高压灌浆措施完成了河湾地块防渗帷幕,帷幕灌浆资料表明坝基及两岸坝肩防渗已满足3 Lu、河湾地块已灌浆段达到5 Lu的防渗设计要求。
Karst landforms dominates the Youchou Hydropower Station Reservoir area, the karst geological problems of river bent area are analyzed to complete its impervious curtain by means of high-pressure grouting. The data of curtain grouting show that the seepage control of dam foundation and abutment on both banks have satisfied 3 Lu, the grouted sections of river bent area have reached seepage control design requirements of 5 Lu.
