SEISMIC RESPONSE OF PILE GROUPS IN LIQUEFIABLE SOIL

Numerical analysis of pile group ina liquefiable soil was considered to investigate the influence of pile spacing on excess pore pressure distribution and liquefactionpotential . The analysis is conducted using a two dimensional plain strain finite difference program considering a nonlinear constitutive model for sandy soil, strength and stiffness reduction and pile -soil interaction.
