Article Title: Behavior of Seismic Soil-Pile Foundation in Liquefying Sloping Ground Controlled by Mechanical Aspect
by Baydaa Hussain Maula (Ph.D)

Abstract:
As far as we know all damages due to earthquake indicate that the presence of liquefaction soil is the primary cause that causes the pile foundation damage. At this point, it's of interest to clarify the relevance of some mechanical aspect effect during quake to incidence the down slope movement. The address of these aspect effects on pile foundation response during earthquake; utilize the solid -fluid fully coupled NDFC "OpenSeesPL". This paper uses an FEM analyses to demonstrate the consequences of the presence of clay layer, the variation magnitude of permeability coefficient (k) and the restrict direction of earthquake. The most significant discovery is to clearly the effect of bi-directional motions on the response of sloping liquefiable ground dynamically through showing high excess pore pressure, larger displacement. Also, its show a phenomena defined by the dilation develops at the bottom of low coefficient of permeability in stratified soil deposits under quake loading which might greatly generate pore water pressures and formation liquefaction which leads attainable slope instability.
Keywords: transverse motion, permeability, nonlinear dynamic finite element, bi-directional; ndfc and downward slope
