摘　　要：夯实法具有设备简单、施工工期短和造价低等优点,在湿陷性黄土地基处理中已被广泛应用。北方黄土高原边缘地带的非典型性黄土由于含水量低、含沙量大、土质不均匀、局部含粘性土夹层等特点,不完全符合有关规范中强夯法的适用条件,结合工程试验,详细分析、探讨了强夯法在该类型地基土中应用的可能性。The dynamic compaction has the advantages of the simple equipment,straight forward in soil improvement principals,short construction period and cos effective.As a result,it has been widely used in the soil improvement projects in loess area.The loess deposits at the edge of the Loess Plateau in northern China are not typical from their formations.They have the characteristics of low moisture and high sandy contents,nonhomogeneous and containing cohesive soil lenses in some areas so that they might not be applicable for the dynamic compaction in accordance with the code requirements.The feasibility of the application of dynamic compaction in this non-typical loess soil formation based on the test data from a case history.
