Analysis of Elastoplastic Mechanical Properties of Non-Uniform Frozen Wall Considering Frost Heave

The aim of this study was to analyze the force and deformation law an artificial frozen wall. Thus, frost heave coefficient introduced describe characteristics, wall regarded as a heterogeneous material whose properties changed in parabolic pattern with radius. elastoplastic stress displacement formulas non-uniform considering characteristics were derived according different strength criteria. Consequently, used calculate mechanical results showed that radial linearly, whereas circumferential change followed after characteristics. Moreover, outer edge always greater than inner edge, increasing temperature, significantly edge. When elastic state, its caused by constant. entered elastic–plastic increased increase radius plastic zone, decreased zone.
