Effect of temperature on the shear strength of .

In the present work, the shear behaviour of soils and the soil–concrete interface is investigated through direct shear tests at various temperatures. A conventional direct shear apparatus, equipped with a temperature control system, was used to test sand, clay, and the clay–concrete interface at various temperatures (5, 20, and 40 °C).

The effect of confining pressure is to increase the density of the soil specimen and hence reduce the void ratio. Dense sand under low confining pressure behaves similar to loose sand under high confining pressure. 3. Characteristics of Saturated Sands during Undrained Shear:

In this paper, a dynamic analysis of strip machine foundation is carried out. The foundation of ple thicknesses is placed at different depths above a saturated sand with different states (i.e., loose, medium and dense), and vertical harmonic excitation is applied with build up of the excess pore water pressure being considered. The dynamic analysis is performed numerically by using finite ...

Different Soils & How They Affect Foundations

Sand/Gravel – Sand/gravel has the largest particles of the different soil types. It is dry and gritty to the touch and does not hold moisture because of the large openings, but drains easily. When compacted and moist it holds together fairly well, and if compacted these make for good soils to support a foundation because of their non-water-retaining properties.

Soil mechanics

Basic characteristics of soils Size range of grains. Aids to size identification; The range of particle sizes encountered in soil is very large: from boulders with a controlling dimension of over 200mm down to clay particles less than 0.002mm (2mm). Some clays contain particles less than 1 mm in size which behave as colloids, i.e. do not settle in water due solely to gravity.
