清江水布垭电站现场固结灌浆试验与分析

Esperiment and Analysis of Consolidation Grouting in Site of Qingjiang Shuibuya Hy dropower Station

介绍了清江水布垭电站在运行水头高、灌浆盖重轻、层状岩体倾角平缓、岩溶构造发育等不利条件下,现场固结灌浆的试验方法与工艺,并对试验数据进行分析,得出了固结灌浆施工必需的设计参数,为复杂条件的固结灌浆积累了经验,供同类大型工程固结灌浆时参考.

The engineering geological condition is complex in Qingjiang shuibuga Hydropower Stationsuchas such as high operating water head,light-weight cover on grout layer.testing method and technology of consolidated grouting in site are introduced and obtained test date are analyzed,design parameters are drawn for consolidated grouting under construction.The experience was accumulated for consolidated grouting in complex condition.The work is very useful for the further similar engineering of consolidated grouting.
