摘　　要：九龙水库位于滇东高原,岩溶发育,坝基渗漏问题严重,采取坝基帷幕灌浆处理措施,对水库建成蓄水具有重要意义。帷幕灌浆试验在坝基灌浆廊道内进行,受场地条件限制,按设计帷幕灌浆孔距、排距进行,为取得灌浆压力、水泥位耗量、待凝时间及灌浆底界等参数,进行坝基帷幕灌浆试验是必要的。通过坝基帷幕灌浆试验,取得了坝基帷幕灌浆压力、水泥位耗量、待凝时间及灌浆底界等设计参数,对设计及后期帷幕灌浆施工具有重要的指导意义。Jiulong Reservoir is located in the east of Yunnan Plateau,Karst is developed,dam foundation seepage problem is serious,taking measures of dam foundation curtain grouting is of great significance to the completion of the reservoir impoundment.The curtain grouting test is carried out in the Grouting Gallery of the dam foundation,which is limited by the site conditions and is carried out according to the designed curtain grouting hole spacing and row spacing,it is necessary to carry out curtain grouting test for Dam Foundation.Based on the test of Dam Foundation Curtain Grouting,the design parameters of dam foundation curtain grouting pressure,cement level consumption,setting time and grouting bottom boundary are obtained.
