| Abstract: | Mechanical tests of frozen soil are essentially a process to obtain the physical and mechanical parameters of frozen soil for engineering design in cold regions and the model parameters in constitutive model of frozen soil.Along with the deepening of research,mechanical behaviors of frozen soil under different loading paths,which are effective approach to verify the existing models,should be investigated more.Thus,precise mechanical tests are fundamental mean to cognize the mechanical properties of frozen s... |
