摘　　要：结合高压旋喷注浆技术在未入岩灌注桩处理中的具体应用实例,分析说明了该技术突破了传统高压注浆技术影响范围的限制,可以在桩底与基岩之间土层深厚的情况下同时解决未入岩灌注桩单桩轴向承载力不足和沉降变形过大的问题,具有较好的加固效果,对类似工程有一定借鉴意义。Combined with the concrete application example of high pressure jet grouting technology in the treatment of cast-in-place pile without rock entry,this paper analyzes and illustrates that the technology can solve the problems of insufficient axial bearing capacity and excessive settlement deformation of single pile without rock entering at the same time,which has good reinforcement effect and has certain reference significance for similar projects.
