AN INSTRUMENTED LOADING RAM FOR TRIAXIAL TESTING OF SOILS

An instrumented loading ram has been developed for conducting drained triaxial tests on large soil specimens. The loading ram consists of three parts: a stem, a compression rod, and a cylindrical shield. Strain gauges mounted on the rod and wired in a 4-arm bridge measure axial strains. The compression rod is made of precipitation hardened stainless steel having a minimum yield strength of 165,000 psi. Thus a linear stress-strain relationship is assured and the error in axial load is small. For example, at an axial load of 5000 lb, the measurement error is plus or minus 25 lbs. /TRRL/
