On the Rheological Behavior of Frozen Soil (Part I)

Abstract

In order to examine the rheological behavior of frozen soil, an experiment of compression in axial direction was carried out, using the samples moulded into cylindrical form with 5cm in diam. and 9cm in height. The results of the experiment were analysed according to the Murayama and Shibata theory for the rheological characters of clay, and it may be considered that the upper yield value of frozen silty clay was between 10 and 20kg/cm^2 at -5℃ and greater than 20kg/cm^2 at -10℃ and also its lower yield value was about 2～4kg/cm^2. The deformation of frozen silty sand was greater than that of silty clay under the same temperature and load in all samples examined here.
