The 2:1 (or 2V:1H) load distribution method is an approximate technique. When compared to the Boussinesq method's integrated solution for the center of a uniformly loaded rectangular area, which statement best characterizes the 2:1 method's typical stress distribution results?
It assumes the load spreads uniformly over an area that grows with depth, causing it to typically underestimate stress at shallow depths but potentially overestimate stress at large depths (z > 4B).
The stress increase is calculated by assuming the soil is an incompressible, purely frictional material (Ļā² > 0, cā² = 0), and is independent of the load aspect ratio.
It consistently yields a higher vertical stress increase (ĪĻzā) at all depths, making it the more conservative approach for foundation design.
It calculates the ĪĻzā based on a failure wedge, making it more accurate for calculating the ultimate bearing capacity rather than settlement.
It assumes the load spreads uniformly over an area that grows with depth, causing it to typically underestimate stress at shallow depths but potentially overestimate stress at large depths (z > 4B).
