摘　　要：高压旋喷技术作为一种有效的地基处理方法,在公路交通、水利建筑等领域应用广泛。目前,高压旋喷技术在设备开发、施工工艺等方面发展迅速,然而该技术涉及的高速射流与土体相互耦合作用机理、高压旋喷成桩形态影响效应、内在机理及其预测评估方法等核心科学问题仍未很好地被科学地认识,这已成为制约高压旋喷地基处理技术的应用拓展及向智能化、低碳化、绿色化发展的关键技术瓶颈。简要综述了高压旋喷成桩机理及形态预测方法的主要研究进展,介绍了高压旋喷技术的基本类型及应用领域,总结了高压旋喷成桩过程中高速射流产生及发展演化特性、高速射流与土体相互作用机理,梳理了对高压旋喷成桩形态有重要影响的旋喷施工参数及土体物理力学性质参数,探讨了用于预测高压旋喷成桩形态的经验法、半经验半理论法、人工智能化,展望了高压旋喷成桩机理及形态预测方法方面值得重视的未来发展及研究方向,以期为高压旋喷地基处理技术领域的工程实践及科学研究提供有益参考。As an effective ground improvement method,high-pressure jet grouting technology finds widespread applications in fields such as highway transportation and hydraulic construction.Currently,this technology witnesses rapid development in terms of equipment development and construction processes.However,the core scientific problems including the coupling mechanism between high-speed jets and soil,the influence of high-pressure jet grouting on pile formation,underlying mechanisms,and prediction and assessment methods are still not well understood scientifically.This has become a key technical bottleneck restricting the expanded application of high-pressure jet grouting ground improvement technology and its development toward intelligence,low carbon,and greenness.This paper briefly reviewed the main research progress in the formation mechanism and morphology prediction methods of high-pressure jet grouting piles and introduced the basic types and application fields of high-pressure jet grouting technology.Meanwhile,it summarized the characteristics of high-speed jet generation,development,and evolution during pile formation of high-pressure jet grouting,as well as the interaction mechanism between the high-speed jet and soil.Additionally,the jet grouting construction parameters and physical and mechanical property parameters of soil that have a significant influence on the pile formation morphology of high-pressure jet grouting were reviewed.Furthermore,the empirical methods,semi-empirical and semi-theoretical methods,and artificial intelligence approaches to predicting the morphology of high-pressure jet grouting piles were discussed.Then,this paper concluded with an outlook on noteworthy future developments and research directions in the formation mechanism and morphology prediction methods of high-pressure jet grouting piles,aiming to provide valuable references for engineering practices and scientific research in high-pressure jet grouting ground improvement technology.
