Soil Mechanics with ...

For engineering purposes, soil is defined as uncemented aggregate of mineral grains and decayed organic matter(solid particles) with liquid and gas in the empty spaces between the solid particles. Soil is used as a construction material in various civil engineering projects,and it supports structural foundations. Thus,civil engineers must study the properties of soil,such as its origin,grain-size distribution,ability to drain water,compressibility,shear strength,and load-bearing capacity. Soil mechanics is the branch of science that deals with the study of the physical properties of soil and the behavior of soil masses subjected to various types of forces. Soils engineering is the application of the principles of soil mechanics to practical problems. Geotechnical engineering is the subdiscipline of civil engineering that involves natural materials found close to the surface of the earth. It includes the application of the principles of soil mechanics and rock mechanics to the design of foundations,retaining structures,and earth structures.
