An unconfined compression test was performed on a soil sample and the axial compressive stress at failure was 42 psi. a) What is the undrained shear strength of the soil; b) State if this test overestimates or underestimates the field shear strength of the soil. Why? c) Which type of soil is most suitable for this type of test.

1. During an unconfined compression test on a stabilized petroleum sludge, the following data were obtained. (a) Plot the stress-strain relationship and determine the unconfined compressive strength (USE MS EXCEL). Note that the original sample length was 20 cm and the original sample diameter was 9.1 cm. (b) How many samples could be put vertically without causing a failure problem to the bottom (the first) solidified sample? Load (kg) 0 510 900 1370 1900 2490 3100 3630 3990 4190 4330...

eslblem 2 25 pt)oe Two triaxial compression tests are conducted on identical specimens of the same saturated clay. In the first test the soil is first consolidated to ?.-350 kPa and u.-200 kPa and then sheared under drained conditions increasing the axial stress while keeping the chamber pressure constant. At failure ?i 560 kPa. In the second test, the specimen is consolidated to ?.-600 kPa and uo-400 kPa, then it is sheared under undrained conditions increasing the axial stress while...

Two undisturbed clay samples were taken from the middle of the
overconsolidated and normally consolidated clay layers in the soil
profile shown. The water table is at the top of the
overconsolidated clay layer. Consolidation tests were carried out
on the two samples and the results are summarized in the table
below. Assume that the bulk, dry, and saturated unit weights of the
sand are 16 kN/m3, 16 kN/m3 and 19
kN/m3, respectively. The specific gravity of the clay
soil...
