Line 1:
Line 1: − '''Geotechnical engineering''' is the field of [[engineering]] concerned with earth materials, such as soils and rocks.+ − − ==Soil mechanics== − Soil mechanics is a key area of geotechnical engineering. Soils are made up of solid rock or mineral particles, water, and air. These three are known as the phases of soil. There are a number of standard properties of soil which are used in geotechnical engineering: − *Unit weight: the weight of a unit volume of soil. − *Voids ratio: the ratio of the volume of voids (V<sub>v</sub>) to the volume of solids (V<sub>s</sub>). − **Porosity: the ratio of the volume of voids (V<sub>v</sub>) to the volume of the soil. − *Shear strength: the shear stress which causes the soil to fail. − − [[Category:Civil Engineering]]
