How are shallow foundations affected by liquefaction?

The results are herein discussed and the most important features are presented that lead to an improved understanding of liquefaction effects on shallow foundations including the nature of the soil and footing response to the different types of loading.

How is earthquake shaking related to soil liquefaction?

The influence of the magnitude of input sinusoidal earthquake shaking was also studied. Both numerical and experimental results showed matching uplift response of the structures and acceleration and pore-pressure measurements in the liquefied soil deposit.
