what is the importance of soil in civil engineering

Importance of Permeability of Soil. Importance of Soil Studies in Civil Engineering: Till the beginning of present century, the importance of study of soil properties was not felt. The particle size ranges from 4.75mm to 80mm. Fills: All manmade deposits of soil and waste-materials are called fills. Cohesion is derived in the fine grained soils […] One of the most important tasks a civil engineer needs to complete is site surveying. Cohesion Angle of internal friction Capillarity Permeability Elasticity Compressibility 1. Swedish soil scientist and chemist Albert Mauritz Atterberg, in the early 1900s, first identified that a gradual decrease in water content of a clay soil slurry causes the soil to pass through different states or conditions. Soils are used as construction materials or the civil engineering structures are founded in or on the surface of the earth. Keep reading to find out why. Civil engineers just design buildings and oversee their construction, right? Engineering Properties of Soil The following properties of soil are taken into consideration while dealing with soil as a construction material. The stability of slopes and retaining structures can be greatly affected by the permeability involved. Cohesion It is the internal molecular attraction which resists the rupture or shear of a material. All the civil engineering structures are supported on or below the surface of the earth; This is applied to all structures whether it be building, bridge or dams. These are the soil embankments raised above the ground surface. Retaining Structure. COHESION It is the internal molecular attraction which resists the rupture or shear of a material. The foundation engineering is an important branch of soil engineering. The knowledge of subsoil conditions at a site is a prerequisite for safe and economical design of sub-structural elements. Engineering properties of fills depend upon the type of soil, its water content and the degree of compaction. Cohesion is derived in the fine grained soils from the water films… Atterberg Limit is a measure of the critical water content in a fine-grained soil. A civil engineer needs to understand the soil behavior of the construction site and to find the satisfactory solution to the soil problem. Geotechnical properties of soils influence the stability of civil engineering … Fig.1. Gravel: It is a type of coarse-grained soil. Cohesion Angle of internal friction Capillarity Permeability Elasticity Compressibility 1. Soils are used as construction materials or the civil engineering structures are founded in or on the surface of the earth. What do engineers have to do with geology? Soil Engineering for Retaining Structures. The type of soil depends on the rock type, its mineral constituents and the climatic regime of the area. Geology is an essential subject for civil engineer services to utilize. Soil is important to civil engineers for various reasons, some of which are described below- Foundations: Almost all the civil engineering structures rest on the soil. Permeability influences the rate of settlement of a saturated soil under load. Most of the important historical buildings were constructed on the basis of experience in the area and knowledge inherited from forefathers. The design of earth dams is very much based upon the permeability of soil used. The following properties of soil are taken into consideration while dealing with soil as a construction material.
