WebThe value for soil spring stiffness is acquired by site testing performed by a qualified Geotechnical Engineer. As a general guide however, here are some ranges of values you can expect for different soil conditions… Soil Type: Modulus of Subgrade (kPa/m) Modulus of Subgrade (MPa/mm) Compacted Sand: 50,000 – 150,000: 0.05 – 0.15: Clay ... WebApr 12, 2024 · E s is soil elastic modulus; R f is the soil failure ratio, with typical value of R f = 0.75~1.0; and ε 50 is the strain corresponding to one half of the maximum principal stress difference. The soil rigidity factor is 200~500 in the collected database, which covers the range for the typical clay suggested by USACE [ 41 ].
WebIn addition to the following, it should be noted that exceptions to typical values of soil properties occur often. All foundations must have a factor of safety applied for design purposes (typically between 2 and 4). Foundations typically need to be taken down to a depth where seasonal changes and plant life will not affect the soil properties.
