摘　　要：高压喷射灌浆技术具有施工简便、速度快等优点,在工程中已被广泛应用。先阐明高压喷射灌浆作用机理,再结合武都水库围堰工程,在砂卵石层中进行单桩试验和围井试验,得出合理的施工参数,指导工程施工,达到防渗效果。High - pressure jet grouting has the advantages of simple construction, rapid speed and so on, therefore it is being widely used in engineering . This paper describes the mechanism of high - pressure jet grouting , and takes the Wudou reservoir cofferdam works for example, drawing reasonable construction parameters by single pile test and surround well test in the sandy pebble layer. The parameter then is used to guide engineering construction and achieve impervious effect.
