It first proposed vortex compression expansion mechanism. Discuss the mechanics conditions of concrete medium squeeze into the soil medium. It describes the vortex compression expanding equipment and the construction process of anchor supporting the soil. The comprehensive results indicate that it’ s feasible to use the method of vortex compression expansion to anchor supporting the soil technology.%提出且验证了涡压挤扩机理，分析了混凝土介质向土体介质中挤入的力学条件，介绍了涡压挤扩细石混凝土锚固支护土体的设备及施工工艺流程，结果表明，采用涡压挤扩方法实施锚固支护土体的施工工艺在理论上是可行的。
