摘　　要：黄河大堤在实施工程淤背后出现堤身裂缝,对裂缝出现的空间进行了研究,结合堤身土的性质及测试成果认为:历次的堤身加高、培厚,存在土质疏松、干密度低及压缩性高的特性,在后期淤背施工过程中,堤身土处于近饱和状态,土体浸水及排水后,由于堤身土的固结作用,引起堤身土的沉陷,因而产生纵向裂缝.建议对这一问题采用土桩挤密法处理.The cracks which occur along Yellow River abutment after the completion of artificial sedimentation. Based on laboratory est results, it is concluded that the earth which forms the abutment shows the characteristics of looseness, low density and high compressibility. The consolidation and settlement of saturated loose soil, which resulted from the artificial sedimentation, develops the cracks along the abutment. Some measures have been suggested to treat this geotechnical problem.
