Soil mechanics - Assignment Example

Running Head: GEOTECHNICS AND DRAINAGE Title: Geotechnics and Drainage Name: Professor: University: Date: Geotechnics and Drainage In geotechnical engineering the techniques of site investigation for soils are well established and so is the topic on soil mechanics.... hellip; soil mechanics This is one of the branches of engineering that mainly focuses on describing how soils behave.... soil mechanics cannot be compared to fluid mechanics because they have a lot of differences since soils have a composition of heterogeneous fluids....

(2006) Essentials of soil mechanics and Foundations: Basic Geotechnics.... 1.... Provide structural framing suitable for sloping and wet terrain with fluctuating water level up to 6".... Chosen foundation must also be sulphate-resistant and be supported by firm strata located below the watertable. The framing is as illustrated in the framing plans in scheme 1....

As such, it is vital to human activities that the properties and conditions of soil are accurately determined so as to ascertain what type of economic activity can take… These analyses are crucial in agriculture, civil engineering and geological study.... There are numerous lab tests that can be performed so as to determine the diverse properties of soil.... The determination of these properties is critical for the design There are different and diverse characteristics of soil; (1) Particle Size, (2) Bulk Density, (3) Consistence, (4) Texture and (5) Water-holding Capacity....

Craigs soil mechanics.... The resisting force exerted by each section is equal to the product of area and unit weight of the material used in the wall, in this case concrete except for section 4, which is made of soil (γ = 115) but acts as part of the wall.... 4) to the driving force offered by the soil to the wall (Craig 189).... The passive pressure is due to the resistance of soil to lateral forces.... The factor of safety, Fsot, as in problem one is the ratio of the summation of resistance moment by the wall to moments due to active thrust of the soil....

Smith's Elements of soil mechanics.... Fundamentals of soil mechanics for sedimentary and residual soils.... he soil sample from the sampler is ejected.... The initial specific gravity and moisture content of the soil is determined.... The ring is rotated to pare off the excess soil by cutting such that the sample is reduced to the same that is inside the diameter of the ring.... The cutting tool is held horizontally while cutting the excess soil....

Critical state is a condition that occurs in the soil where shear distortions develop without effective stress, void ratio and deviatoric stress changes (Schofield 1998).... As such, soil and associated granular materials attain a critical state after they get a continuous… As such, the maximum shear stress, which the soil can bear, gives the shear strength of the soil.... Excess shear stress results in the failure of the soil, which may occur mostly because of catastrophic loading on the The soil attains a critical state when there is a constant shear stress and no further volumetric strain occurs....

"soil Elastic Modulus Measurement Using Triaxial Test" paper argues that the elastic modulus and soil stiffness depend on the consistency and density of the given soil under investigation.... nbsp;… The triaxial test is a procedure performed in most laboratories; the test is used to determine the shear strength parameters for a variety of soil types under different conditions.... The conditions include drained and undrained soil property....

"Experiments on soil mechanics" paper argues that it is important to take great caution when loading the machine with weights because incorrect loading can damage one's back.... hellip; The placement of the soil in glass in the rotating machine is risky.... The casa grande test is usually used in determining the soil's liquid limit.... This test can be used on various varieties of soil although the dried soil is mostly preferred as illustrated by Head (2006)....
