Soil Mechanics (Geotechnics - Essay simulationSoil is composed of particles such as silt, clay, gravel and sand and they can too contain other(a) gases that exist in between these particles. The study of defacement is very important because this is what makes the study of geotechnical engineer possible. This is a subtopic in civil engineering and it is a very complex topic. Soil mechanics is applicable in many ways as far as building and construction is concerned and some of the dress hat examples are such as building foundations of bridges, dams and sustaining systems of buried pipelines. This is very important because it ensures that buildings do not pin tumbler apart well in the modern domain of a function and this contributes a lot to the development of different cities world wide. The study of soils is also very important because it contributes a lot to good agricultural products. Many areas of engineering depend on soil mechanics and some of these areas are such as coa stal engineering, geophysical engineering and hydrology among other areas. One of the best ways of approaching the topic on geotechnics and drainage is by means of understanding the composition and genesis of soils. This is one of the best examples of a diagram that clearly defines the institution of soils as far as volumes of water supply, air and solid is concerned. The V?, V?, and Vs re bear the amount of solids, air and water present in a specific mixture of soil. W?, W?, and Ws in the diagram above stand for the weights of solids, air and water within a soil mixture and M?, M?, and Ms stand for the masses of water, solids and air found in a mixture of soil. The formulae for calculating the weights of all the named particles present is Mass multiplied by the acceleration of gravity which is Ws=Mg. Types of Triaxial Tests There are several types of triaxial tests but the just about common ones are Consolidated Drained also known a CD, Consolidated Undrained tests which is al so referred to as UD and Unconsolidated Undrained. In the consolidated drained or CD, the test is done through consolidating and cut back while compressing it with the drainage. In the second type of test, the sample is not drained and in the terzetto type of test, the sample is constantly compressed. This is an example of soil horizons from www.wikipedia.com . A can be referred to as the colluviums or top soil, B is the Residual soil that is mature and C is weathered rock. In most cases, soil deposits become affected by how they are transported to the specific location where they can be found. Understanding the formation and deposition of soils makes it quite easier and understandable especially when it comes to dealing with geotechnics calculations. Clay is composed of several minerals that form structures that behavior like a sheet which have a length range of 10 x 10 ?7 and 4 x 10?5 and its thickness ranges from 9 x 10?9 and 2x 10?6 and their surface area is large. Through un derstanding the formation of soils, one can easily understand how different stresses and shears are formed in different phases on a standard circumstance and all this is part of the study of geotechnics (Chen 2010). Stress rail line submit diagram. Looking at the curve above, one can easily predict the stability of the soil by measuring the shear strain against its shear strength Cell pressure kN/m2 Deviator stress kN/m2 kN/m2 2 (a). Normal and Over- Consolidated Stratum commonly consolidated stratum is one which is very dense and packed tightly as one goes cryptical the strata. An over-consolidated clay stratum is one which occurs when water is squeezed out of the ground with
