註釋Part I of this research deals with two types of triaxial tests where consolidation or prestress loading is applied, (1) while maintaining a constant ratio of principal stresses or (2) while maintaining zero radial strain. A set of fundamental static triaxial stress-strain and shear strength performance ratings are developed based on the controlling influences of soil identification, relative density, and triaxial prestress and load history. Part II covers development of apparatus for studies of wave propagation in a confined sand column with the input supplied by an air pulse from a pneumatic shock tube. A special specimen container was constructed to provide restricted radial strains while allowing unimpeded axial motion, thus approximating plane wave conditions. Stress guages were designed and placed to record passage of a single wave front.
