摘　　要：深圳抽水蓄能电站高压岔管区洞室内水压力高,为论证深圳抽水蓄能电站高压岔管区采用钢筋混凝土衬砌的可行性,进行了现场水力劈裂试验,测试裂隙岩体的抗劈裂能力和相应的P-Q曲线。试验结果表明:岔管围岩的劈裂压力大于1.2倍的内水压力。因此在做好防渗设计的基础上,采用钢筋混凝土衬砌方案是可行的。In order to verify the feasibility of reinforced concrete lining at the high pressure turnout of Shenzhen Pumped Storage Power Plant, a field investigation of hydrojacking was done at site. Test results and P-Q curves show that the jacking pressure of surrounding rockmass is i. 2 times higher than internal water pressure. Therefore, on the basis of the effective anti-seepage design adopted, the reinforced concrete lining at the high pressure branch is feasible.
