摘　　要：高压喷射灌浆技术被广泛应用于水利水电工程围堰防渗、桩基施工。此项施工技术取得成功的关键在于使用合适的高喷泵及合理地使用喷射压力、喷嘴直径、喷射流量等参数。结合某高喷泵及水利水电规范的高喷施工参数,探讨了高喷参数的合理取值范围,并利用理论公式研究各参数之间的相互关系。High-pressure grouting technology is widely used in cofferdam anti-seepage and pile foundation construction of hydropower engineering.Key points of the technology are choosing appropriate high-pressure grouting pump and reasonable parameters such as grouting pressure,nozzle diameter and grouting displacement etc.Based on parameters of a high-pressure grouting pump and the ones in hydropower codes,value range of high-pressure grouting technology is suggested.Further,interrelations among the parameters are discussed by theoretical formulas.
