Webis an empirical coefficient related to the soil's corn- pressibility and degree of saturation. For saturated soils, B = 1. 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- WebAdd the soil to the mixture and mix for 5-6 minutes. Clean the blade as no material should be lost. Place the mixture in a 1-liter cylindrical container and fill it with distilled water. Place a rubber cap on top of the cylinder and turn the container upside down multiple times.
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… Webthese engineering properties of soil is very critical for analysis of a geotechnical engineering problem.
