摘要
简析湿陷性黄土填方的现状,针对湿陷性黄土地区地基施工,着重阐述了强夯法的优势及施工步骤。结合工程实例,具体论证了湿陷性黄土高填方地基强夯处理的关键技术,通过对地基承载力、回填土质的湿陷性以及回填土密实的均匀度等指标的检测,地基加固效果显著,使湿陷性黄土高填方地基获得了较高的地基承载力和密实度,解决了回填区与原土区结合部不均匀沉陷、广大黄土地区湿陷性黄土高填方回填地基处理等问题。
This paper briefly analyzes the present situation of collapsible loess fill,focusing on the advantages and construction steps of dynamic compaction method in view of foundation construction in collapsible loess area.The key technology of dynamic compaction treatment of collapsible loess high fill foundation is demonstrated.Through testing the bearing capacity of foundation,the collapsibility of backfill soil and the uniformity of backfill soil density,the effect of foundation consolidation is remarkable.It makes the collapsible loess high fill foundation obtain higher bearing capacity and compa ctness,and solves the problems of uneven settlement in the junction between backfill area and original soil area,and the treatment of collapsible loess high fill backfill foundation in the vast loess area.
