摘　　要：为优化超高水头钢筋混凝土衬砌水道高压固结灌浆设计参数,结合高压隧洞裂隙岩渗透稳定研究,在抽水蓄能电站利用1∶1原型试验洞,系统性开展高压灌浆试验、安全监测和岩体力学试验。结果表明:不同围岩类别固结灌浆参数得到优化,提出断层带的最优加强灌浆方式和Ⅱ类围岩化学灌浆的必要性。该研究可为超高压隧洞围岩稳定性分析、支护和防渗处理及超高水头钢筋混凝土水道合理设计提供参考。In order to discuss the design parameters of high pressure consolidation grouting for super high head reinforced concrete lining waterway,the high pressure grouting test,safety monitoring and rock mechanics test were carried out systematically for the first time in pumped storage power station by using 1∶1 prototype scientific research test tunnel combined with the study of seepage stability of fractured rock in high pressure tunnel.The parameters of consolidation grouting for different types of surrounding rock were optimized,the optimal strengthening grouting method for fault zone was recommended,and the necessity of chemical grouting for typeⅡsurrounding rock was discussed.The results could provide reference for the revision of specifications and the rational design of super high head reinforced concrete waterway in the future.
