Shape: The pressure bulb is typically depicted as a three-dimensional shape, often resembling an inverted cone or pyramid. It extends downwards from the base of the loaded area or foundation into the soil.
Distribution: Within the pressure bulb, the pressure is not uniformly distributed. It is highest at the base of the loaded area and decreases with depth. The pressure distribution is influenced by factors such as the shape and size of the foundation, the load magnitude, and the properties of the soil.
Depth: The depth of the pressure bulb varies depending on the characteristics of the foundation and the soil. Deeper foundations will have deeper pressure bulbs.

What are the importance of pressure bulb?
The Zone in a loaded soil mass bounded by any arbitrary isobar is known as a pressure bulb. The vertical pressure at any point on the surface of the pressure bulb is the same.
Why the principle of effective stress important in soil mechanics?
coz at the end of structure construction soil grains are the one whic carry the load so useful in analysis of bearing capacity of granular soil
A final year project topics on soil and water engineering?
Soil Mechanics & GeoTechnical EngineeringSoil LiquefactionReady mix concrete plantsPile foundationImprovement of bearing capacity of sandy soil by groutingGround improvement techniqueUse of plastic as soil stabilizerErosion control in slope
Would you expect the suction in the soil to be 0 at any time?
Soil suction is zero at the phreatic surface. This is the point where the pore water pressure is equal to the pore air pressure. Above this surface pore water pressure becomes increasingly negative compared to pore air pressure and as such matric suctions develop. Below the phreatic surface the pore water pressure becomes increasingly positive and the pore spaces are totally saturated.
What is the difference between bearing capacity and bearing pressure?
bearing capacity is the capacity of soil or strata that can be able to sustain the load of superstructure in the unit of load per m2 either ton/m2 or KN/m2 bearing pressure is nothing but bearing capacity example when you apply 100 KN on a unit area, equal opposite pressure will rise from the soil. load / area = bearing capacity

How can pressure bulb of a foundation influence depth of soil investigation?

Why soil mechanics as a separate discipline from the general mechanics?
Soil mechanics is a discipline in which application of laws of mechanics and fluid mechanics are applied where as in mechanics laws of physics are applied
How do you define soil?
define soil crusting
What is cell pressure in soil mechanics?
Axial pressure is sigma1 (the load that is applied from above) Cell pressure is sigma3 (the load that is applied horizontally) (Civ Eng III student)

What is equipotential line in soil mechanics?
lines that all the points on it have the same head pressure and eqipotential lines are always prependicular to the stream lines .

What is the difference and connection between soil mechanics and foundation engineering?
soil mechanics is the science dealing with soil to knowing ,type of soil , bearing capacity of the slackening weakness and strength of the soil and by soil mechanics can we give a recommendation to the designer Foundation engineering is design of foundation of any projects ,building ,factories ,stores ....)the design of foundation type depended on the bearing capacity of the soil of the concerned site of the project.
