Bearing Capacity Flood- Proof and Frost Proof: Key Formulas

Question 1

What is the Odemark formula for determining soil layer thickness?

Answer 1

E2=k×E3

Where:

𝐸2= Elastic modulus of improved soil (MPa)
𝐸3= Elastic modulus of subsoil (MPa)
𝑘= Empirical coefficient (2 to 4)
​

Question 2

What is the frost penetration equation?

Answer 2

ℎ𝑣=𝛼×𝐼

Where:

ℎ𝑣= Frost depth (m)
𝛼= Insulation factor
𝐼= Frost index
