METHODS OF REDUCING LIQUEFACTION HAZARDS

There are basically three methods of reducing hazards liquefaction hazards: 1)  By Avoiding Liquefaction Susceptible Soils Construction  on liquefaction susceptible soils is to be avoided. It is required to characterize the soil at a particular building site according to the various criteria ...

CAUSES OF LIQUIFACTION OF SOIL

Liquefaction is the phenomena when there is loss of strength in saturated and cohesion-less soils because of increased pore water pressures and hence reduced effective stresses due to dynamic loading. It is a phenomenon in which the strength and stiffness ...

APPLICATIONS OF SOIL MECHANICS

The knowledge of soil mechanics has application in many fields of Civil Engineering. 1. Foundations The loads from any structure have to be ultimately transmitted to a soil through the foundation for the structure. Thus, the foundation is an important part of ...

CONTACT PRESSURE AND DEFORMATION PATTERN

The shape of the deformation pattern varies depending on flexibility of the foundation and type of soil. Figure 1 illustrates the relative distribution of soil contact pressures and displacements on cohesion less and cohesive soil. Linear contact pressure distributions from ...

BASIC DEFINITIONS IN GEOTECHNICAL ENGINEERING

A soil mass consists of solid particles which form a porous structure. The voids in the soil mass may be filled with air, water or partly with water and partly with water. Soil is a three ...
