Abstract
This paper reports the findings of a series of triaxial compression tests performed on saturated specimens of compacted clay and dense sand at axial strain rates ranging from 0.01 %/min to 800 %/min. The purpose of these tests is to provide a baseline for the shear strength of near surface soils during buried explosions, and to evaluate the transition from conventional quasi-static experimental soil mechanics to faster rate testing. The behavior of the saturated clay and sand specimens under undrained loading is examined in detail using pore water pressure measurements at the boundary, which permits evaluation of the impact of the rate of loading on the effective stress paths during shearing.
