WebThat is, soil pressure equals a soil constant times the d e f o r m a t i o n : p = ky where: p = soil pressure, psi k = modulus of subgrade re- action y = deformation, inches The subgrade modulus has units of pounds per square inch (psi) per inch of deformation, commonly written as pounds per cubic inch (pci). WebIn soil mechanics, dilatancy is the volume change observed in granular materials when they are subjected to shear deformations. [1] [2] This effect was first described scientifically by Osborne Reynolds in 1885/1886 [3] [4] and is also known as Reynolds dilatancy. It was brought into the field of geotechnical engineering by Peter Walter Rowe [ de].
