STRENGTH BEHAVIOR OF AN ANISOTROPICALLY CONSOLIDATED REMOLDED CLAY

IF A SOIL SPECIMEN IS CONSOLIDATED UNDER ANY CONDITIONS OTHER THAN THOSE TO WHICH IT HAS BEEN PREVIOUSLY SUBJECTED, ITS STRUCTURE WILL BE ALTERED AND A CHANGE IN ITS STRENGTH CHARACTERISTICS WILL RESULT. THIS INVESTIGATION IS CONCERNED WITH THE EFFECT OF THE SECONDARY INHERENT STRENGTH ANISOTROPY CAUSED BY VARIATION OF THE CONSOLIDATION STRESS PATH AND THE PRINCIPAL CONSOLIDATION STRESS RATIO OF THE STRENGTH RESPONSE OF A HOMOGENEOUS CLAY REMOLDED TO POSSESS A GIVEN PRIMARY INHERENT ANISOTROPY. BASED ON THE RESULTS OF THIS LIMITED STUDY, THE FOLLOWING CONCLUSIONS MAY BE DRAWN. STRENGTH CHARACTERISTICS ARE INFLUENCED BY THE INITIAL SOIL STRUCTURE BEFORE ANISOTROPIC CONSOLIDATION, OR PRIMARY INHERENT STRENGTH ANISOTROPY, AS WELL AS THE STRUCTURAL REARRANGEMENT OF PARTICLES DUE TO ANISOTROPIC CONSOLIDATION, OR SECONDARY INHERENT STRENGTH ANISOTROPY. THE STRESS PATH FOLLOWED TO OBTAIN A GIVEN PRINCIPAL CONSOLIDATION STRESS RATIO INFLUENCES THE SOIL RESPONSE. PORE PRESSURE VALUES DURING A STRENGTH TEST DECREASE WITH INCREASING VALUES OF THE PRINCIPAL CONSOLIDATION STRESS RATIO. WITH ONE EXCEPTION, THE RESPECTIVE FAILURE STRAINS FOR BOTH THE MAXIMUM AND THE MAXIMUM FAILURE CRITERIA WERE APPROXIMATELY EQUAL. WATER CONTENT FOR A GIVEN OCTAHEDRAL NORMAL CONSOLIDATION STRESS DECREASES WITH INCREASING VALUES OF THE PRINCIPAL CONSOLIDATION STRESS DIFFERENCE. /AUTHOR/
