consolidation settlement

Although Terzaghi's conventional linear one-dimensional model [16] can be adopted to predict the ultimate primary consolidation settlement for the foundation, the in situ consolidation is a three-dimensional problem with varying coefficients of consolidation [15, 17].

For this edition he also reorganizes the material--for example splitting the chapter on allowable bearing capacity of shallow foundations into two chapters: one on estimating vertical stress due to superimposed loading, and the other on elastic and consolidation settlement of shallow foundations.

Immediate settlement is analyzed by using three methods, Timoshenko and Goodier's method, Janbu's method and Schmertmann's method for sand while consolidation settlement is used for the estimation of the settlement of clay layer.

When settlement reaches design consolidation settlement, the surcharge load can be removed.

Other topics include estimating the elastic and consolidation settlement of foundations, dynamic bearing capacity and the associated settlement, materials and techniques for reinforcing foundations, and estimating ultimate uplift capacity.

Consolidation settlement is decrease in voids volume as porewater is squeezed out of soil, occurs slowly according to permeability.

In most preloading projects, the prediction of the consolidation settlement and lateral displacement of the ground is an essential design requirement.

Skempton and Bjerrum proposed a correction factor ([mu]) to modify one-dimensional consolidation settlements to bring out two- and three-dimensional effects [11].
