CALCULATION OF ANTI-HEAVING CUSHIONS

RASCHET PROTIVOPUCHINNYKH PODUSHEK

The thickness of anti-heaving cushions or the height of the hoisting are ordinarily defined so that the soil beneath the cushions (or, generally speaking, beneath the non-heaving soil) will not heave. The limit of the heaving stays somewhat away from the border of the freezing. This is equal to .5 m at a freezing depth of 1.0-1.5 m and -.15 at a freezing depth over 2 m. This article elaborates a twelve-step operational calculation in order to develop the subject. Extremely detailed figures are included to illustrate the computations.
