Effects of Strain Rate in Consolidated-Undrained Triaxial Compression Tests of Cohesive Soils. Report 2. Vicksburg Buckshot Clay (CH)
The results of consolidated-undrained (R) triaxial compression tests with pore pressure measurements performed to determine the effects of strain rate on the strength and deformation characteristics of Vicksburg buckshot clay (CH) are presented and analyzed in this report. The 1.4-in.-dia triaxial specimens were compacted with a Harvard miniature compactor to 95 percent of maximum dry density derived from the standard effort compaction test with water contents 2 percentage points wet of standard optimum. Standard caps and bases (having the same diameter as the test specimen, with 1-in.-diam rigid porous inserts and drainage connections) were used in the triaxial tests. After back-pressure saturation and consolidation under effective confining pressures of 0.5 and 5.0 kg per sq cm, specimens with an without filter strips were axially loaded at rates of strain varying from 1.2 to 0.0012 percent per minute. Data presented include stress-strain curves, pore pressure observations, final water content distributions within the specimens, and shear strength envelopes based on total stresses. (Author)
