Phi in soil mechanics
The active state occurs when a retained soil mass is allowed to relax or deform laterally and outward (away from the soil mass) to the point of mobilizing its available full shear resistance (or engaging its shear strength) in trying to resist lateral deformation. That is, the soil is at the point of incipient failure by shearing due to unloading in the lateral direction. It is the minimum theoretical lateral pr… WebSoil mechanics 1 has different formulas both in theory as well as in lab.

For an elastic material, A = 1/3. For soils that compress under shear, A > 1/3, and for soils that dilate under shear, A < 1/3 Under the fully drained condition, the excess pore pressure is zero, and pore pressure in satu-
