黄土的湿陷性是黄土在一定压力下受水浸湿结构发生破坏的现象，在湿陷性黄土地区进行工程建设时,必须进行地基处理。在充分分析黄土湿陷性的机理及其影响因素的基础上，探讨将高能级强夯法应用于湿陷性黄土的地基处理方法，从高能级强夯法加固黄土的效果的理论分析出发，将该法应用在实践工程中，经试验检测其加固效果较好，不仅消除了黄土湿陷性，还提高了黄土的强度，该法对湿陷性黄土地基处理具有较高的应用价值。

Loess collapse is a hazard phenomenon of loess structure destruction in immersion, so collapsed loess must be treated in constrction. On the basis of analyzing and studying the mechanism of loess collapse and their affecting factors, the paper discusses the method that is used for studying the collapsed loess foundation with dynamically high energy level compaction. Meanwhile, the method has achieved good effect in fieldtest, so it will have better application value.
