Deformation Measuring System for Repetitively Loaded, Large Diameter Specimens of Granular Material

摘要

The report describes the design and evaluation of a deformation measurement system developed to observe the vertical and horizontal displacements of points on the surface of large diameter cylindrical specimens of granular material subjected to rapid, repeated load applications. The system consisted of a loading apparatus, triaxial cell, measurement transducers including a newly developed optical tracker, and recording apparatus. (Author)
