Soil Engineering. Foundations Paragraph A What is Soil Engineering? Soil Engineering is a stream of geotechnical engineering, which exclusively deals with understanding the characteristics and mechanics of soil. Soil engineering helps in analyzing the structure and composition of the soil of the proposed construction site, thus helping in deciding whether the soil of the proposed construction site or building is worth exploiting. Apart from this, soil engineering also deals with providing optimized design concepts and construction techniques according to the composition and physical properties of the soil. It is also concerned with taking various soil tests that helps in correct interpreting what field conditions are safe or unsafe for construction works and for the personnel working there. Paragraph B I Types of soil I Technically, soil is a mixture of rock and mineral particles, water and air. It is on the basis of these constituents that the properties of the soil differ from area to another. Moreover, different types of soils behave differently to the construction works. The type of soil has a huge influence on the design and expenses of the building to be constructed. Also, different type of soil requires different foundations to ensure a stable construction process. For example, clay sand requires additional materials in the foundation as the clay might swell or shrink depending on the water content, thus leading to cracks in the walls and foundation. Paragraph C Methods Involved It is to note that the properties of the topmost layer of the soil might differ from the surface below it. For this reason samples are taken by subsurface exploration to understand the soil conditions below. Subsurface exploration is done by using various methods such as digging pits, trenches, boring and cone or standard penetration tests, which allow continuous recording and testing of soil properties that change with depth. Some of the common works of soil engineering include landslide repairs, constructing seawalls, shoring and underpinning. Paragraph D Types of foundations A foundation is a structure that transfers loads to the earth. Foundations are generally broken into two categories: shallow and deep foundations. A shallow foundation is usually embedded a meter or so into soil. One common type is the spread footing which consists of pads of concrete or other materials which extend below the frost line and transfer the weight from the walls and columns to the bedrock. Another common type is the slab-on-grade foundation where the weight of the building is transferred to the soil through a concrete slab placed at the surface. A deep foundation is used to transfer a load from a structure through an upper weak layer of soil to a stronger deeper layer. There are different types of deep foundations including helical piles, impact driven piles, caissons, piers and earth stabilized columns. Paragraph Е I Foundation Design Considerations Foundations are designed to have an adequate load capacity with limited settlement by a geotechnical engineer, and the foundation itself is designed structurally by a structural engineer. The primary design concerns are settlement and bearing capacity. When considering settlement, total settlement and differential settlement are normally considered. Other design concerns include scour and frost heave. Scour is when flowing water removes supporting soil from around a foundation (like a pier supporting a bridge over a river). Frost heave occurs when water in the ground freezes to form ice lenses. Specific Features of Foundations I

Верен ли перевод данного отрывка? It would not be cheap to drive very large currents through these cables. Large currents need very thick wires. If thin wires are used, they get hot or melt, and so the currents ought to be as small as possible. Не дешево направлять ток большой силы по такому кабелю. Для тока большой силы необходимы очень толстые провода. Если используются тонкие провода, они будут нагреваться и плавиться, и поэтому необходимо, чтобы сила тока была как можно слабее.
