After the recovered sample was examined, pieces <br /> <br />of the sample were selected and stored for laboratory testing. Four <br /> <br />2-la inch Shelby tubes were advanced in an attempt to obtain <br /> <br />undisturbed samples for laboratory testing. Two Shelby samples Were <br /> <br />taken in Borehole Number One (BH-1). one at twenty-five feet and one <br /> <br />a t fifty feet. The remaining two samples were taken in Borehole <br /> <br />Number Two (BH-2) at twenty and thirty foot depths. Only partial <br /> <br />samples Were recovered. A full twenty four inch sample was not <br /> <br />obtained in any of the four samples. <br /> <br />2. Laboratory Testing <br /> <br />A laboratory testing program was completed to determine the <br /> <br />index properties of the soils profile and the approximate strength <br /> <br />parameters of the soils. <br /> <br />The laboratory testing program included direct shear tests on <br /> <br />undisturbed samples at a confining pressure of 5000 pounds per square <br /> <br />foot. Moisture and density analyses were performed on all samples, <br /> <br />Il-3 <br />
