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

What is the shear strength in terms of effective stress on a plane within a saturated soil mass at a
point where the total normal stress is 295 kN/m² and the pore water pressure 120 kN/m²? The effective
stress parameters of the soil for the appropriate stress range are c= 12 kN/m² and 5=30°.
