-2- <br />Swell-Consolidation Tests: Swell-consolidation tests were conducted <br />on sartg~les of the soils from the site in order to determine their ~~ <br />compressibility or swell characteristics under loading arc] saturation. <br />Each sample was prepared and placed in an pedometer ring between <br />porous discs, and an initial seating load which was 1,000 psf for this <br />project was placed on the sample. The sample was then saturated by <br />inundation with water, and the percent change in original sample <br />height was measured bi' means of a dial gauge. Samples which swelled <br />subsequent to saturation were loaded incrementally until returning to <br />their original height. The sample height was monitored until <br />deformation practically pealed under each load increment. <br />If the sample did not swell, it was loaded incrementally until a <br />straight line relationship between load and strain was obtained. The <br />consolidation test procedures described are similar to P31M procedure . <br />Ir2435. The results of the consolidation tests are plotted as a curve <br />of the final strain at ead~ incc~nent of pressure against a log of the ' <br />acaamilated pressure. St+ell-consolidation test results are presented <br />in Figs. B-1 through B-7. ' <br />Triaxial Shear Tests: Triaxial shear testing was performed on <br />relatively undisturbed soil sanQles. In a triaxial test, a <br />cylindrical specimen is subjected to an all around pressure ard, in <br />addition, an axial pressure varied independently of the all around <br />pressure is applied. The all around pressure is applied in a <br />fluid-filled chamber and the axial load is applied by means of a <br />piston passing through the dumber top. <br /> <br />
