their behavior under stress and strain in idealized conditions. In practice, natural soil deposits are not homogeneous, elastic, or isotropic. In some places, the stratification of soil deposits even may change greatly within a horizontal distance of 15 to 30 m. For foundation design and construction...
Chapter 4 Soil Properties
A part of the voids is occupied by water, and the remainder by air. The volume occupied by water being measured by the volumetric soil moisture content is defined as total volume volume of water θ= (7) Hence 0 ≤ θ ≤ n; the soil moisture content is equal to the porosity when the soil is saturated....

Dec 23, 2014· Liquefaction is a phenomenon where saturated sand and silt take on the characteristics of a liquid during the intense shaking of an earthquake. It take place when a ....
ELECTRICAL RESISTIVITY TEST OF SOIL
Apr 18, 2015· Dense clean sand above the water table, for example, would exhibit a high resistivity due to its low degree of saturation and virtual absence of dissolved salts. Saturated clay of high void ratio, on the other hand, would exhibit a low resistivity due to the relative abundance of pore water and the free ions in that water....

The inside of the model test box was made as smooth as. possible to reduce friction with the edges of the model. foundation during the application of load. The model foundation was made of hard wood with. dimensions of 76 mm (width) X 229 mm (length) X 38. mm (thickness)....
Basics of Foundation Design UniFI
any foundation design. Indeed, foundation design requires a solid understanding of the principally simple, but in reality very complex interaction of solid particles with the water and gas present in the pores, as well as an indepth recognition of the principium of effective stress. To avoid the easily...

13. AN INTRODUCTION TO FOUNDATION ENGINEERING
These foundations types are illustrated in Fig. The most common type of foundation is the footing which consists of an enlargement of the base of a column or wall so that the pressure transmitted to the foundation material will not cause failure or excessive settlement. In order to reduce the bearing pressure transmitted to the foundation...
DETERMINATION OF DYNAMIC SOIL PROPERTIES .
Figure 2 shows a schematic of the typical cyclic behavior of soils. As the soil element looses stiffness with the amplitude of strain, its ability to dampen dynamic forces increases. This is due to the energy dissipated in the soil by friction, heat or plastic yielding....
