On the Rheological Behavior of Frozen Soil (Part II)

Abstract

In order to examine the rheological behavior of frozen soil, an experiment of flexure was carried out, using the samples moulded into beam with 4cm square cross-section and 50cm span length. The equation which represented the deflection of frozen soil beam, was derived from certain assumptions usually accepted in elastic bending, on the basis of the Murayama-Shibata theory for the rheological characters of unfrozen clay. The result of the experiment was analysed by this equation and the important creep factors σ_0 and B_2E_2 in their theory were evaluated for frozen soil. These values of factors were compared with those calculated from the experiment of axial compression of the same frozen soil, as already reported in Part I. Comparison showed fairly close agreement.
