VERTICAL AND LATERAL VARIABILITY OF VANE SHEAR TEST DATA FOR A CLAYEY SOIL
Keyword(s):
Vane shear (VS) strength in the upper 2 m of a relatively uniform clay soil varied both vertically and laterally. Obtaining VS values which are reliable at the 80% confidence level for the transect tested required measurements at three sites for a depth increment within the upper meter, but a single site would be adequate for depth increments between 1 and 2 m. A preferred procedure to that of characterizing a modal pedon is outlined for estimating VS strength in soil survey. Key words: Vane shear, variability
