摘要
采用ＡＤＩＮＡ程序对用旋喷桩加固的复合地基进行了弹塑性有限元分析，研究了加固前后地基承载力及刚度的变化，并探讨了复合地基的破坏机理．
An Elasto Plastic FEM analysis is performed for the composite foundations strengthened by the whirling ejector pile using the ADINA program. The variety of load bearing capacity after strengthening is studied. The failure mechanism of the composite foundations is also discussed in this paper.
