Subsurface conditions were defined by a total of 16 s~mple borings located as shown
on the Plan of Borings, Plate 1. The borings were advanced between sample
intervals using auger drilling procedures. The results of each boring are shown
graphically on the Logs of Borings, Plates 2 through 17. Sample depth, description,
and soil classification based on the Unified Soil Classification Syut~m. are shown on
the logs of borings. Keys to the symbols and terms used on the logs of borings are
presented on Plates 18 and 19.
Undisturbed samples of cohesive soils were obtained with Shelby tube samplers at
the locations shown on the logs of borings. The Shelby tube sampler consists of a
thin-walled steel tube with a sharp cutting edge connected to a head equipped with
a ball valve threaded for rod connection. The tube is pushed into the undisturbed
soils by the hydraulic pulldown of the drilling rig. The soil specimens were extruded
from the tube in the field, legged, tested for consistency with a hand penetrometer,
sealed, and packaged to maintain "in situ" moisture content.
The consistency of cohesive soil samples was evaluated in the field using a calibrated
hand penetrometer. In this test a 0.25-inch diameter piston is pushed into the
undisturbed sample at a constant rate to a depth of 0.25-inch. The results of these
tests are tabulated at respective sample depths on the logs. When the capacity of
the penetrometer is exceeded, the value is tabulated as 4.5+.
