摘　　要：详细论述了加蓬国大布巴哈水电站引水隧洞水力劈裂试验的原理、试验设备、试验过程,并对最终得出的数据进行统计分析,评价引水隧洞在高压水头作用下裂隙张开的可能性及张开后岩体裂隙渗透特性,从而指导引水隧洞衬砌设计,优化钢衬段长度。This paper goes into details on the principles,test apparatus and test process of the hydraulic fracturing test of the power tunnel of the Great Poubara Hydropower Project in Gabon,makes a statistical analysis of the data obtained from the test and evaluates the possibility of fissure opening of the power tunnel under a high pressure water head and permeability of rock mass after opening of fissures,thus guiding both the lining design of the power tunnel and the optimization of the length of the steel lining.
