, subsurface exploration, for a proposed landfill in Tippeconoe County.
The estimated undrained shear strength values of the cohesive samples are included on the boring logs
. The estimated shear strength values generally increase with depth (Davis, Booker 1973).
Therefore, boring logs
included topsoil thickness at each boring.
It was clear that this must be the elusive "blue," "blue-green," and "green" of the historic CECOS boring logs
dating back to the early 1970s.
Each run retrieves core samples or drill cuttings, which are visually inspected and compiled into boring logs
based on a system of soil and rock classifications and interpretation.
Soil profiles were taken from boring logs
adjacent to each footing row, and profile sketches were made of each pile showing tip elevations, cutoff elevations, and other essential pile information.
