摘要
介绍了高压喷射注浆的施工技术、用途，影响极身强度的因素。讨论了喷射注浆工程的设计计算，并对灌注桩基轴向承载力计算公式作了修正，进而提出旋喷注浆工程设计中桩基承载力的计算公式，经在两项工程设计计算中应用，说明是可行的。
This paper describes the technique of high pressure jet grouting and its usage as well as the influence factor for the carrying capacity of pile.The design and calculation of spinning jet grouting is discussed. The formular of the carring capacity of piled foundation is processed with the technique of spinning jet grouting.It has been used in two projects and proved practicable.
