摘要：引汶济消工程三河口水利枢纽大坝坝基唯幕准浆具有防渗性、移定性及提高坝基岩石整体性的作用：该工程地处泰岭腹地南北气候分界线地带特殊区城，确定碳压混凝土拱坝坝基的淮聚参数，尚缺乏依据和经验，三河口水利枢纽大坝坝基惟幕灌浆试验研究成果表明：通过合理的布孔间排距、灌浆压力、灌浆水灰比及单位注入量、灌后检查标准等浆参数，可以有效的保证大坝坝基惟幕灌浆的施工质量，该试验成果已成功应用于本工程中，并可为类似坝基惟幕灌浆施工提供依据，

(Hanjiang-toWeihe River Valley Water Diversion Project Construction CO. , LTD. , Shaanxi Province, Xi'an 710010O, China) Abstract : The dam foundation curtain grouting of Sanhekou Water Control Project in water diversion from Hanjiang River to Weihe River has the function of improving seepage stability and rock integrity . In order to ensure the construction quality of dam foundation curtain grouting, it must be based on reasonable grouting parameters .The RCC dam foundation is in the Qinling hinterland in north-south climate boundary zone . How to determine the grouting parameters of RCC dam foundation is still a question because of less basis and experience . Through this experimental study , this paper summarizes the curtain grouting parameters of RCC arch dam foundation in this special area , and provides the basis for dam foundation grouting construction. The results of the curtain grouting test of Sanhekou Water Control Project show that the grouting parameters can effectively ensure the construction quality through reasonable grouting interval , grouting pressure, grouting water-ee ment ratio and unit injection amount and grouted checking standards , the experimental results have been successfully applied to the project.
