摘要: The mechanical properties of a saturated frozen sand were studied using constant axial stress creep tests and strain-rate tests. Observation the effects on deformational behavior produced by addition particles to ice matrix led an analysis useful in predicting rates for levels strain rate. relationship between rate polycrystalline considers dependent hardening term energy softening term. Parameters equation include temperature. Stress factors, volume concentration friction dilatancy sand, are used conjunction with give predictions sand-ice system. These reasonable agreement experimental data.
