CREEP CHARACTERISTICS OF SANDS

ABSTRACT This study is concerned with the creep characteristics of sands under constant principal stress differences of various stress levels which were experimentally obtained by drained triaxial compression tests. In these tests, in order to obtain the creep behavior which is due only to the principal stress difference, but excluding the effect of variation of mean effective principal stress, both the mean effective principal stress as well as the precompression stress of the sand specimens were kept at the same value. The results of these tests are consistent with those predicted by the equations based upon the rheological model previously proposed by Murayama (1983).
