RESIDUAL STRENGTH IN CONVENTIONAL TRIAXIAL TESTS

A METHOD OF ANALYSIS OF RESIDUAL STRENGTH IS PRESENTED WHICH TAKES INTO ACCOUNT HORIZONTAL COMPONENTS OF LOAD AFTER THE FORMATION OF A SHEAR PLANE IN THE CONVENTIONAL TRIAXIAL TEST. SOURCES OF ERROR ARE CONSIDERED AND IT IS SHOWN THAT ALTHOUGH RELATIVE DISPLACEMENTS ARE LIMITED, CONSISTENT RESULTS ARE OBTAINED IF THE AXIAL LOAD IS ACCURATELY MEASURED. COMPARISONS ARE MADE OF PEAK AND RESIDUAL STRENGTHS OF LONDON CLAY, PIERRE SHALE AND A CONSOLIDATED FINE SAND. FROM THE RESULTS OF TESTS ON PRE-EXISTING FISSURES AND ON REMOULDED SAMPLES, IT IS SHOWN THAT RESIDUAL STRENGTHS, WHICH MAY CONVENIENTLY BE OBTAINED IN THE TRIAXIAL TEST, ARE IN FAIRLY CLOSE AGREEMENT WITH THE PROBABLE LOWER LIMIT OF RESIDUAL STRENGTH AT LARGE STRAINS. /AUTHOR/
