ELASTIC AND CONSOLIDATION
SETTLEMENT
Dr. Arlyn Aristo
▪ Elastic settlement or immediate settlement, yaitu penurunan yang
bersifat langsung setelah diberikan pembebanan.
▪ Consolidation settlemen, yaitu penurunan yang terjadi
bergantung pada waktu, atau time dependent settlement. Pore
water is extruded from the void spaces of saturated clay soils
submerged in water.

Foundation load is assumed distribute linearly
A rigid foundation is shown the figure. Calculate total settlement of the
Foundation!
Note: Settlement consist of elastic settlement on sand and clay
and consolidation settlement on clay.
On clay layer use 2:1 method for stress distribution
