IMPORTANCE OF DYNAMIC SOIL PROPERTIES
Earthquake, ground vibration, and wave propagation through soils
Dynamic stress, deformation, and strength properties of soils
Dynamic earth pressure problem
Dynamic bearing capacity problems and design of shallow foundations
Problems related to soil liquefaction
Design of foundations for machinery and vibrating equipment
Design of embedded foundations and piles under dynamic loads
Stability of embankments under earthquake loading
USES OF DYNAMIC PROPERTIES
Shear Wave Velocity, Vs
For Soil Characterization
As Particle motion is perpendicular to the wave motion, so it can be used for determining shear properties of soil skeleton. (Show)
Shear Modulus, G
Used for defining stiffness matrices in FEM of Earth structures and foundation soils
Damping Ratio, D
Ability of System to absorb dynamic energy
Controls the duration and mode of Vibration
