Title: SAMPLING A GLACIAL SILTY CLAY
Accession Number: 00179012
Record Type: Component
Availability: Find a library where document is available Abstract: Over a period of 10 years a total of 42 borings were made in a glaciolacustrine deposit on the western boundary of Detroit, Michigan. The soil profile consisted of yellow-brown mottled silty clay underlain by gray silty clay. The undrained shear strength, moisture content, and dry density of 329 soil specimens of the gray silty clay are statistically analyzed. The variables are randomly distributed in both the vertical and the lateral directions. The lognormal distribution is the most likely fit for the data but, on engineering grounds, the normal distribution is preferred. Statistical estimation theory indicates that as few as 5 borings arranged in an X pattern and containing at least 30 specimens could adequately estimate the values for design at this site. /Author/
