Experimental Study of the Accumulation Dynamic Residual Strain of Ice under Rail Traffic Loading

Abstract:

Based on dynamic tri-axial test at low temperature, deformation behavior of ice is studied under stepped axial cyclic loading. Time history curves of residual strain of ice are investigated under different negative temperatures and frequencies. Conclusions can be drawn as follows: dynamic residual strain rate increases with the increasing of stress ratio and frequency, while decreases with the decreasing of temperature. According to test data, power function is brought forward to fit the relation between stress ratio, negative temperature, frequency and dynamic residual strain rate. Then, the effect of fitting parameters by temperature and frequency was investigated.
