What is the soil mechanics?
soil mechanics primarily refers to a sub -group of building engineering that studies soil properties when used as building material or as a basis. In a larger sense, this may also include the study of land weathering and by wind and water. The formation process determines many physical properties of soil, such as structure, composition and relative density. How these properties can affect the construction project is examined by engineering methodology, which include the mechanics of fluids and the mechanics of materials. Especially worrying in the soil mechanics is how the soil at a given location will respond to the tension that puts the requirements of the project on it.
From the engineer's point of view, the soil is layers of free non -stratified material on the Earth's surface, which results from the decay of rocks. It usually holds a certain amount of water, can contain organic material and rest on the underlying fixed layer. The soil mechanics is unique in that engineers often have little control over theCorps of the main component of the project. Adaptation must be made on the soil properties as located on site.
These variable properties are the product of the process of geological formation and local climatic factors. The soil mechanics of the site can be expected to sampling to create a soil profile. Generally the profile examines three layers that can be divided into component layers if necessary
The upper layer is generally rich in organic material and is rarely more than 15 feet (4.6 m) depth. Below is a layer of about 2 feet (0.61 m) deep, fine -grained, chemically active material that was stored from above. The lowest layer essentially remains in the same geological state as when it is first stored and can be extended down by more than 100 feet (30.5 m). Road disadvantages and foundations of light living or commercial buildings usually depend on the properties of the secondary layer.Large clay constructs, such as dams or dams, usually consist of a material collected from the lowest level.
Several common soil structures can be categorized according to their mineral composition, chemical properties and particle arrangement. The behavior of each varies in response to compression, angular tension and water flow. Building engineering applies physical sciences such as liquid and mechanics of material to determine the soil mechanics for a specific location. This analysis can exclude a website for a specific project or indicate the modifications necessary to continue.
Knowledge of soil mechanics is critical in many aspects of building engineering. All structures are based on the foundation that is built in relation to the properties of the soil. The design of the road depends on how the basic soil reacts to stress and changes due to saturation or water temperature URE. Underground structures, such as tunnels and pipes, are a dynamic interplay of soil properties, methods of construction and materials components.
