| 英文摘要 | The resistance to deformation of artificially frozen soils in deep alluvium is investigated by relation between the secant Young's modulus and the axial strain at different types of soil, loading way, negative temperature and initial confining pressure. It is observed that the stress-strain behavior of frozen soils in deep alluvium is highly nonlinear and the frozen soil secant Young's modulus may decay with increasing strain. The limit of the elastic stage appeared similar for all conditions, and was found to be approximately 0.05% axial strain. On the other hand, the secant Young's modulus of studied frozen soils and its degradation was heavily responsive to the type of soil, loading way, negative temperature and initial confining. pressure. Results indicate that the factors which can increase the secant Young's modulus before frozen soils yield would accelerate the rate of degradation of the secant Young's modulus after frozen soils yield, (c) 2005 Elsevier B.V.
