Learning Objectives

Upon completion of this course you will:

• Learn about the three components of soil settlement;

• Learn how superimposed loads cause pore pressures to increase, forcing water from compressible stratum which decreases volume and causes settlement;

• Learn how stresses exceeding the present effective vertical pressure of overburden produce preconsolidation;

• Learn about the mechanisms of settlement for coarse-grained soils;

• Learn how to use shape and rigidity factors to calculate settlements of points at the surface of an elastic half-space;

• Learn how to calculate the magnitude of immediate settlement in clay;

• Learn a method for calculating instantaneous settlement of isolated footings on coarse-grained soils;

• Learn how the typical loading cycle during building construction may cause swell and heave during foundation excavation, followed by application of the structural load which recompresses subsoil and may extend consolidation into the virgin range.

• Learn how to use pressure-void ratio diagrams.

• Learn how to correct settlement calculations for overconsolidated clays that may give an overestimate of the settlement.

• Learn the relationship between the Settlement Ratio and the Overconsolidation Ratio.

• Learn about the relationship between initial shear stress and the overconsolidation ratio; and

• Learn about the time rate of primary consolidation..
