强夯法在黄土地区某高填方工程中的应用

Application of Dynamic Compaction in High Fill Project in Loess Area

在湿陷性黄土地区的大型土石方工程中,采用强夯法处理高填方填筑体,与传统的分层碾压法相比有较大的优越性及较好的经济效益。结合工程实例,介绍了高填方强夯施工工艺、排水设计和质量控制标准,提出了高填方强夯地基需要解决的问题及处理措施,有效地预防了高填方工程最易发生的工后沉降和不均匀沉降问题。

In large earth and rock engineering in collapsible loess area,dynamic compaction is adopted in high fill project and it is superior economic compared with normal method.Based on engineering practice,the author introduces construction technology,drainage design and quality control standard,puts forward some problems and treatment measures which successfully prevent settlement after construction and uneven settlement.
