[案例四]
[背景]
某水电站大坝为混凝土双曲拱坝,坝高240m,总库容58亿m3,装机容量6×55万kW年发电量约172亿kWh。固结灌浆施工于1994年12月开始施工,1999年3月全部完成。
(1)地质简况和岩体质量分级。根据岩石强度、岩体结构、围压效应、水文地质条件等多种因素将岩体类型分为:①优良岩体(A~C级),可直接作为大坝地基;②一般岩体(D级),经过灌浆处理后可作为大坝地基;③较差岩体(E3级),自然状态下原则上不宜作为高坝地基;④软弱岩体(E1、E2级),不能直接作为坝基,需特殊处理;⑤松散岩体(F级),不能作为主体建筑物地基。
(2)坝基固结灌浆设计。①设计原则。根据岩体质量情况,灌浆设计分为常规灌浆和特殊灌浆两大类,前者适用于A、B、C级岩体,后者适用于D、E两类岩体。②灌浆材料。常规灌浆使用42.5级普通硅酸盐水泥。特殊灌浆原则上Ⅰ、Ⅱ序孔为普通硅酸盐水泥,Ⅲ序孔为磨细水泥。
(3)固结灌浆质量检查。灌浆质量检查显示固结灌浆效果良好。
