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.

A rectangular block is 129 mm long in the X direction, 100 mm wide in the Y direction, and 56 mm thick in the Z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as follows: 213 kN tension in the X direction, 193 kN tension in the Y direction, and 230 kN compression in the Z direction. If v = 0.3 and E = 198 GPa, determine the single uniformly distributed load in the X direction that would produce the same deformation in the Z direction as the original loading. Answer must be in kN.
