Optimal Pile Arrangement for Minimizing Excess Pore Water Pressure Build-Up

Numerical analysis of pile group in a liquefiable soil was considered to investigate the influence of pile spacing on excess pore pressure distribution and liquefaction potential. The analysis is conducted using a two-dimensional plain strain finite difference program considering a nonlinear constit...
