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.

本文通过现场足尺试验,研究了水泥搅拌桩的荷载传递规律。结果表明,传到桩端的荷载占桩顶荷载的比例甚小。桩体的变形、轴力和侧摩阻力主要集中在0~l_c(临界桩长)深度内。当外荷增大时,会使0~l_c深度内桩体的变形增大,但当深度大于l_c时,桩体变形、桩身轴力和侧摩阻力随外荷的增大变化均较小。水泥搅拌桩的破坏发生在浅层,破坏形式为环向拉裂或桩体压碎。在弹性范围内,桩身应力有限元计算值与实测值较一致。
