The following two statements are made with respect to different sand samples having the same relative density. Identify if they are TRUE or FALSE. I. Poorly graded sands will have lower friction angle than the well graded sands. II. The particle size has no influence on the friction angle of sand.
A clayey soil has a maximum dry density fo 16 kN/m3 and optimum moisture content of 12%. A contractor during the construction of core of an earth dam obtained the dry density 15.2 kN/m3 and water content 11%. This construction is acceptable because.
The ratio Nf/Nd is known as shape factor, where Nf is the number of flow lines and Nd is the number of equipotential drops. Flow net is always drawn with a constant b/a ratio, where b and a are distances between two consecutive flow lines and equipotential lines, respectively. Assuming that b/a ratio remains the same, the shape factor of a flow net will change if the
Two series of compaction tests were performed in the laboratory on an inorganic clayey soil employing two different levels of compaction energy per unit volume of soil. With regard to the above tests, the following two statements are made. I. The optimum moisture content is expected to be more for the tests with higher energy. II. The maximum dry density is expected to be more for the tests with higher energy. The CORRECT option evaluating the above statement is
Identify the two FALSE statements from the following four statements. I. The consolidation of soil happens due to the change in total stress. II. When Standard Penetration Tests are performed in fine sands below the water table, the dilation correction is applied after the overburden correction is applied. III. Over consolidated clay's will have predominantly cohesive strength as compared to the frictional strength. IV. Compaction of soils is due to expulsion of water.
A borrow pit soil has a dry density of 17 kN/m3. How many cubic meters of this soil will be required to construct an embankment of 100 m3 volume with a dry density of 16 kN/ m3
An infinite slope is to be constructed in a soil. The effective stress strength parameters of the soil are c = 0 and = 30 . The saturated unit weight of the slope is 20kN/m3 and the unit weight of water is 10kN m3. Assuming that seepage is occurring parallel to the slope, the maximum slope angle for a factor of safety of 1.5 would be
A deep cut of 7 m has to be made in a clay with unit weight 16 kN/m3 and a cohesion of 25 kN/m2. What will be the factor of safety if one has to have a slope angle of 30 ? Stability number is given to be 0.178 (from Taylor s chart) for a depth factor of 3.
In a drained triaxial compression test, a saturated specimen of a cohesion less sand fails under a deviatoric stress of 3 kg/cm2 when the cell pressure is 1 kgf/cm2. The effective angle of shearing resistance of sand is about
A braced cut, 5 m wide and 7.5 m deep is proposed in a cohesion less soil deposit having effective cohesion c = 0 and effective friction angle, = 36 . The first row of struts is to be installed a depth of 0.5 m below ground surface and spacing between the struts should be 1.5 m. If the horizontal spacing of struts is 3 m and unit weight of the deposit is 20kN/m3, the maximum strut load will be
