NON-COHESIVE SOILS’ COMPRESSIBILITY AND UNEVEN GRAIN-SIZE DISTRIBUTION RELATION

UDK: 624.134

E.A. Gaikov, A.O. Zubov

In this issue the results of laboratory investigation of soil compression phases with consideration of various granulometric composition are presented. Considering grain-size distribution allows to refine technological requirements for artificial soil structures, backfills, sand beds. Further studies could be used for developing standard documents, SP45.13330.2012 in particular. It is shown, that soil density is correlating with deformability parameters only for the same grain-size distribution. Basing on the test results it is shown, that compaction ratio is not sufficient for deformability estimating without grain-size distribution taken into account. Experimental soil box with microscale video recording for compression phases studies is described. Photo and video materials showing the differences of microscale particle movements were obtained for non-cohesive soils with different grain-size distribution. Analysis of the compression tests results and elastic and plastic deformations separation allows to identify each compression phase.
