Load Transfer Behavior of Cement Treated Soil Column

Load transferbehavior of cement treated soil column is studied by conducting full scale ieldtest.Results showed that the percentage of load transferred to the column end is small.The deforma-tion,axial stress and frictional resistance of column shaft occurred mainly within the depth 0～l_c（l_c: thecritical column length）.As the total load increased the shaft deformation,the axial stress and the fric-tional resistance increased greatly within the depth 0～l_c but they increase little for the depth below l_c.Failure of the column occurs mainly at the shallow depth under high compressive stress,and the failurepatterns of the column are of annular tension cracks and/or brittle cracks. In the elastic range,theaxial stresses by FEM are in agreement with measured results.
