Influence of the sloping ground conditions and the subsequent shaking events on the pile group response subjected to kinematic interactions for a liquefiable sloping ground

The soil-pile kinematic interaction under large nonlinearity, including soil liquefaction, represents a complex phenomenon that depends on many unforeseen factors. This paper presents the results of dynamic centrifuge tests carried out considering varying sloping inclination angles for liquefiable ground subjected to four successive earthquake shakings having an increasing amplitude acceleration. indicated surface inclinations have significant influence bending moment response piles. significantly larger moments were generated downslope pile compared upslope highlighting non-existence shadowing effects during lateral spreading ground. first shaking, predominant substantially than following three shakings, indicating depend not only base excitation; but mostly magnitude spreading. Moreover, influences E.P.W.P was studied and it found piles may receive maximum around occurrence liquefaction time initiation dissipation phase E.P.W.P. • Centrifuge modeling involving 5° 10° sloped 2X2 group.
