摘　　要：木里河立洲水电站引水隧洞沿线工程地质条件和水文地质条件较为复杂,均应对隧洞围岩进行固结灌浆,提高围岩的整体性,降低围岩渗透系数,充分利用围岩的承载能力,形成一定范围的围岩固结圈,达到与衬砌结构联合受力的目的。因此,在引水隧洞固结灌浆工作大范围展开之前,通过灌浆试验来确定各项参数是非常有必要的。笔者根据该工程的地质条件、试验目的和试验内容,将灌浆试验分为三段试验区,以获得合理的灌浆参数、适合的灌浆工艺,从而指导灌浆工程的实施,保证各标段引水隧洞固结灌浆的可靠性并达到节约灌浆工程投资的目的。There are complex engineering geological and hydrological conditions along the headrace tunnel of Lizhou Hydropower Station on the Muli River.The tunnel and surrounding rocks require consplidation grouting so as to imporove the overall stability of surrounding rocks,reduce the permeability coefficient of surrounding rocks,form a surrounding rock stereosphere within a certain scope,and achieve joint stress together with lining strueture.Therefore,it is required to determine parameters by means of glouting test before the consolidation grouting works of headrace tunnel are carried out within a wide range.
