摘要
本文介绍采用强夯方法使抛投在淤泥中的堆石体挤开淤泥,形成人工置换地基或部分置换地基的整式挤淤、桩式挤淤方法及工程实例;阐述强夯平台填料及结构尺寸选择原则。在淤泥中采用强夯挤淤方法形成道路、码头及其他建筑物地基,见效快,成本低,承载力可达250～500kPa以上。
In this article, it introduces the theory and practice on pressure ramming of silt soil foundation. i. e., the pressure ramming of riprap-body replaces its surrounding sill and will form an artificial underpinning or a partial underpin- ning; thus eventually it can afford the foundation treatment of integrating riprap as pile into the silt and making a stronger foundation. It demonstrates with some engi- neering examples and describes the riprap feed Platform system and the requirements of its structural construction and respective dimensions etc. This silt foundation treat- ment method, has been widely used in the construction of highways, ports and build- ing foundations, and proved as of high efficiency, low cost and a strengthened silt soil bearing capacity over 250~500k Pa.
