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.

It is known that the clay stratum is normally consolidated. using Skempton's
equation, determine the net safe bearing capacity of the footing. Compute
the settlement that would result if this load intensity were allowed to act on
the footing. Natural water table is quite close to the ground surface.

A stratified soil is to be analyzed for stresses. The stratified soil is composed of sand, silt, clay and gravel. The 2.80-m thick gravel underlays the 3.60-m thick clay while the 4.0-m thick sand which overlays the 3.0-m thick silt is overlain by the gravel. Ground water table is at a depth of 8.0-m from the surface of the stratified soil. Soils above GWT are dry. Use the given soil properties below, draw the complete soil profile and perform the following requirements: For sand: Yd = 16.35 kN/m³, Ysat = 19.62 kN/m³ For silt: Yd = 19.35 kN/m³, Ysat = 22.22 kN/m³ For clay: Yd = 17.35 kN/m³, Ysat = 20.82 kN/m³ For gravel: Yd = 18.35 kN/m³, Ysat = 21.52 kN/m³ Note for 1a, 1b, 1c, and 1d that there is no capillary rise in the soils.
