A level site underlain by fully saturated clays is cut over a few days as shown in the figure below. The water table is located at the ground surface across the site. Determine the resisting moment in kN.m for the circular slip surface depicted in the Figure below shortly after excavation. Consider the soil wedge above the circular slip surface as a single free body, whose plane area is equal to 100 m2 and the centre of gravity of the soil wedge is given at Point C.

A sample of soil (0.1 m X 0.1 m) is subjected to the forces shown in Figure below. Determine (a) σ1, σ3, and α;(b) the maximum shear stress; and (c) the stresses on a plane oriented at 30° counterclockwise from the major principal stress plane.

An embankment load on a silty clay soil layer as shown below. Determine the stress increase under the embankment at points A and B that are loaded at a depth of 6 m below the ground surface, please use figure (10.20). 5 m 1Н:2V, 1H:2V 1H:1V 8 m y=18 kN/m y=18 kN/m" 6 m : B Figure 10.19 Embankment loading 0.50- 3.0 20 16 0.45- 14 1.2 LO 0.40 - 0.9 0.8 0.7 0.35 - 0.6 030- 05 04 * 025 - 03 0.20 - 0.2 0.15 - 0.10 - 0.1 0.05- Figure 10.20 Osterberg's chart for determination of vertical stress 0.00 TI TT - due to embank- 01 0.1 10 ment loading 100 327
