INITIAL EXCESS PORE PRESSURE IN SOILS

The purpose of this note is to present a Newmark type of influence chart to estimate the instantaneous excess pore pressure in deep, homogeneous soils due to surface vertical loads of any arbitrary but finite shape. It is concluded that assumption of Boussinesq type distribution for instantaneous excess pore pressure could result in gross overestimation of consolidation settlement. The analysis has particular reference to flexible loaded finite areas, such as liquid storage steel tanks. A chart is developed to assess the instantaneous excess pore pressure below flexible loaded areas of arbitrary shape.
