Performance based design
Static Liquification
MIT-S1
Predicts instability
undrained loading
based on void ratio & stress history
models accurately
Strain softening
critical state transition
Useful assessment
triggering in sands with variable density
critical for
offshore foundations
tailing dams
pipeline burial
Particle Crushing and Scale Effects
LCC defines high-pressure comp. curve
particle breakage
drives settlement
under large foundations
deep stress
regardless of initial density
Explains scale effects
Large footings
Settle more due higher crushing
modeling is more robust
void ratio based not as good
captures non-linear stiffness
increase with confining stress
more accurate than
HC
MC
