Concept explainers

Methods to Determine Vertical Stress

The load applied to the soil is transferred to the underground. The presence of water at soil pores and solid grains above the soil are the primary components that are responsible for the effective load transfer. Due to the load acting, the internal component of the soil or the underground formations undergoes deformations or a tectonic shift. The amount of deformation depends upon the amount of load acting on the soil surface, which indeed, depends on the weight of everything present above the soil. Due to this, the underground soil element develops internal stresses which try to resist the tectonic changes.

Question

Select TRUE or a FALSE for the following statements.
1) The void ratio of any soil cannot exceed 1.0.
2) Unconfined compression test results depend on the confining pressure.
3) The failure envelope makes an angle o with the axis of the normal stress in
Mohr circle plot.
4) The total settlement of a clay layer depends on its coefficient of permeability.
5) The angle of internal friction is always equal to zero in fully saturated clays
during the unconsolidated undrained (UU) test.
