Unified analysis of liquefaction and the ground flow phenomenon

Loose saturated sand behaves as a solid before liquefaction but as a fluid when the excess pore water pressure equals the initial confining stress, after which it recovers its strength. A simple constitutive equation for loose saturated sand was developed to express the phase transformation between a solid and fluid during liquefaction and the ground flow phenomenon. This constitutive equation was used for a shaking table test, and its applicability was investigated by comparing numerical and experimental results Published in Prikladnaya Mekhanika, Vol. 43, No. 8, pp. 129–144, August 2007.
