复合载体夯扩桩的工程特点及其应用

The Technical Characteristics of the Rammed Piles with Compacted Composite Base

复合载体夯扩桩是在钢筋混凝土沉管灌注桩扩底的基础上 ,针对软弱地基或松散填土地基的特点对扩底进行填料、夯实挤压来提高桩的承载能力的一种地基处理技术 .对复合载体夯扩桩的工程特点和施工工艺进行了介绍 ,并以工程实例说明了复合载体夯扩桩处理地基的优势 .

On the basis of the technique of cast-in - place pedestal pile,the technique of the rammed pile with compacted composite ba se,to improve the conditions of the soft ground base and the loose earth-fillin g, pursues a greater bearing capacity by filling materials to the spread base an d then ramming it compacted.An account is given on the technical characteristics and technical requirements.The advatages of this technique are illustrated by a project item.
