Abstract:Based on the engineering practice and testing results by various inspection met
hods, the combining method with the deep mixing method around the rigid pile to compact and strengthen the soft soil is presented and discussed.The concept of rigid piledeep mixing pile composite ground is put forward.The computation methods of bearing capacity，and the test method of rigid piledeep mixing pile composite ground are  presented.The
engineering practice proves that the rigid piledeep mixing pile composite ground has the advantages of good technical and economic effects.
Keywords:rigidflexible pile； composite foundation； composite modulus；bearingcapacity
