强夯置换碎石墩在沿海某石化铁路工程中的应用研究

Application and Study on Dynamic Compaction and Replacement of Macadam Pier in the Coastal Petrochemical Railway Engineering

强夯法施工技术具有高效、经济、环保等优点,近年来在我国地基处理领域得到了广泛的应用。着重介绍了强夯置换碎石墩在沿海某石化铁路专用线软基处理中的应用。该工艺解决了滨海复杂地层软基处理中常规复合地基不成桩、同时有邻近既有建筑振动破坏影响的问题,为类似工程的设计和施工提供参考。

The dynamic compaction technique has the advantages of high efficiency,low cost,and environmental protection,for which in recent years it is widely used in foundation treatment in China. This paper introduces the application of macadam pier by dynamic compaction and replacement method in the coastal petrochemical special railway line in soft foundation treatment. The process solves difficult pile formation in the soft foundation treatment in coastal complex formation of conventional composite foundation,and damage caused by adjacent building vibration,which provides the reference for the design and construction of similar engineering.
