水电工程建筑物超高压灌浆是一个全新的课题。天荒坪第二抽水蓄能电站天然落差约730 m，为研究以及探索水工隧洞高水头作用对隧洞围岩的整体性和抗变形能力的影响，在天荒坪PDX1探洞进行压力高达12 MPa的灌浆试验，由于所采取施工方法和措施均较恰当，促使整个灌浆顺利进行，获得了合理的灌浆程序和参数，为高压水头大型混凝土衬砌水道灌浆提供实践依据。
水電工程建築物超高壓灌漿是一箇全新的課題。天荒坪第二抽水蓄能電站天然落差約730 m，為研究以及探索水工隧洞高水頭作用對隧洞圍巖的整體性和抗變形能力的影響，在天荒坪PDX1探洞進行壓力高達12 MPa的灌漿試驗，由于所採取施工方法和措施均較恰噹，促使整箇灌漿順利進行，穫得瞭閤理的灌漿程序和參數，為高壓水頭大型混凝土襯砌水道灌漿提供實踐依據。

Ultra-high pressure grouting of hydropower project building is a new subject.The natural fall of the second pumped storage power station of Tianhuangping is about 730m, 12MPa grouting experiment was carried out in PDX1 testing tunnel of Tianhuangping to study and explore the impact of high water head in hydraulic tunnel on the integrity of tunnel surrounding rocks and deformation resistance.By the smooth progress of the entire filling based on the appropriate construc-tion methods and measures, reasonable grouting procedures and parameters were obtained, which could be the practical ba-sis of large concrete lining grouting with high pressure water head.
