Construction Process

In civil engineering, construction is the combination of art and science, to construct a physical and naturally built environment, starting from the design phase. The construction process falls under the area of building construction, which is a sub-branch of civil engineering. Hence, it is also sometimes called the design and build or design-build process. The work of construction is majorly carried out by civil engineers and design professionals along with a team of works consisting of contractors and subcontractors.

Question

SITUATION: In accordance with Boussinesq theory, the vertical
stress at a point below the center of flexible circular area in a
semi-infinite homogeneous isotropic soil mass due to uniform
load is given by the expression:
P = q(1 --)
Where
N= (1+(R/z)?)3/2
R= radius of circular area
z = depth of interest at which stress is induced
q = intensity of pressure on the circular area (load per unit area
at the base of the footing)
%3D
How deep, in meters, below the footing would the pressure be reduced by 1/10 of the pressure
at the base of the footing.

Please give me both answers right solution Soil mechanics, Mohr's circle An element of soil at the point of failure is represented as a square with effective stresses applied to it as normal (σ') and shear (τ) stresses. If (σ'a, τ) = (54,12) kPa and (σ'b,τ) = (20,12) kPa, determine the angle of shearing resistance for the soil φ' in degrees (°) to 1 decimal place.

write all step is clearly pls you give me different solution why
Which of the following statements are correct (select all that apply) ? Group of answer choices Boussinesq’s equations can be used to estimate the increase in total vertical stress within the soil below the foundation of a circular tank resting at the ground surface as long as the entire soil profile is linear-elastic, homogeneous and isotropic. The principle of superposition of loads can be used to combine the increase in vertical stress from various surface loads as long as long the underlying soil profile is homogeneous. If a soil profile consists of a soft clay layer near the surface underlain by a very stiff clay layer, Boussinesq’s equations would tend to over-estimate the increase in vertical stress within the upper soft clay layer due to a surface load. The influence depth associated with a surface load corresponds to the depth beyond which the relative increase in vertical stress after loading is negligible.
Note: Kindly give me ALL answers otherwise leave it. Thank you
