The mechanical properties of scrap tire crumbs-clayey soil mixtures, such as shear strength, residual shear strength, unconfined compressive strength, and consolidation settlement, were explored by a series of laboratory tests.
The estimation of consolidation settlement is one of the most important procedures in the design of soft ground improvement projects .
Although Terzaghi's conventional linear one-dimensional model  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].
It appears that the value of [C.sub.ns] has significant influence on consolidation settlement
. It is worth noting that associate flow rule ([C.sub.ns] = 10) is assumed during consolidation analysis for all the three cases.
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.
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 (1957) proposed a correction factor ([micro]) to bring three-dimensional consolidation effects in one-dimensional consolidation settlement
Skempton and Bjerrum proposed a correction factor ([mu]) to modify one-dimensional consolidation settlements
to bring out two- and three-dimensional effects .
