摘　　要：介绍了一种新型的挤密灰土桩即强力夯扩挤密灰土桩。通过改进夯填工艺和改造夯锤的外形尺寸和重量 ,达到了大幅提高地基承载力的目的。在成孔方面 ,采用了较大功率的振动沉拔桩机 ,使得成孔深度有了较大提高。有效解决了拔管困难的问题 。In this paper a new type compaction lime soil pile as strong force rammed expansion lime soil compaction pile is introduced. Through the improvement of puddle backfill technology and modification of the dimension and weight of hammer ram the purpose as enhancing the bearing strength of foundation is achieved. In the drilling hole aspect the vibratory driver extractor is adapted. It raises the depth of drilling hole and solves the problem of difficultly extracting pipes. An effective way to solve the collapsibility of over thick collapsible loess is found.
