The shear box test on soil

The shear box test has an advantage over test because of the simplicity of equipment used and the ease in setting it up. The Shear test box also tests soil samples under different conditions such as consolidation, drainage, and saturation conditions. Another advantage of the shear box test is that it is easy to visualize what is happening to the soil as the test is being carried out. Various processes using the shear box test determine these properties. In determining the soil, these properties the results of the test are tabulated and graphs are drawn. Interpretation of the graphs is what gives significant meaning to some of the soil properties being studied. Purpose of the test A shear box test is used in geotechnical engineering to test various properties of soil. These soil properties include; friction angle, peak shear strength, soil cohesion, and the residual shear strength of the soil being studied. The key purpose for carrying out the test is to enable geotechnical engineers decide on the consolidated-drained shear strength of a silt to sandy soil. Shear strength is a very important aspect in engineering when determining soil properties. This is because most structures are based on soil’s shearing strength or resistance. Therefore, any time a structure is to be constructed it is important that the soil’s shear resistance be analyzed as the first step to decide on the whether it will be possible to construct. ...

From the chart we have D10 = 0.2 D30 = 0.45 D60 = 1.20 So Coefficient of uniformity is = D60/D30 Cu = 1.20/0.2 = 6.0 And Coefficient of curvature of the soil is = D302/(D10 x D60) Cc = 0.452/(0.2 x 1.2) = 0.84375 (iv) From the particle size distribution chart we can see that the particles are distributed over a wide range. So, this is a well graded soil.

Steel building design
At the same time, the design should also ensure and provide the necessary comfort, energy-efficiency and safety to the inhabitants. To attain the fundamental building requirements, it is then necessary to integrate adequate structural resistance to building designs. The primary purpose of this is to sustain the actions (i.e. loads, imposed displacements, thermal strains) and influences resistance so that the building will remain serviceable and durable (Brettle, 2009). Meanwhile, in order to secure the structural safety of the building during its intended life, it should be designed and…

Soil Mechanics (Geotechnics
Soil is composed of particles such as silt, clay, gravel and sand and they can also contain other gases that exist in between these particles. The study of soil is very important because this is what makes the study of geotechnical engineering 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 best 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…

Hardness Test
This paper explores a report on the use of the Rockwell test to determine the hardness of various materials. Rockwell scale involves a scale of hardness that relies on hardness indentation of a material. This test is used to determine the extent of hardness through taking the measurements of the penetration depth of an indenter on a load that is large in comparison to the preload’s penetration. During testing, the hardness indentation is linearly correlated to the tensile strength. These traits are vital because they allow the non-destructive bulk metal testing to occur. The obtained data is…

Soil strengthening of age-old-designed railway tracks
The response to the cyclic loading of rail track is an interaction of superstructure and substructure. Ballast, sub-ballast, and sub-grade relates to substructure. Decades of operation bring structural changes of substructures. The sub-grades of the old existing rail tracks require rehabilitation to satisfy proper functioning and meet current technical operational standards. The scope of this assignment is to find the rehabilitation approach for the existing tracks of Australia. The solution must account that improvement of substructure by dismantling the railways is not an option due to the…

Shear box
Introduction In soil mechanics, the term shear strength describes the magnitude of a shear stress that the soil can sustain (Roscoe 34). On the other hand, shear resistance of a soil occurs as a result of interlocking of particles and particle friction and possibly the bonding or cementation at particle contacts (Roscoe 45). Particle interlocking may cause a material to contact or expand in volume because of being subjected to shear strain (Poulos 560). As soil expands in volume, the density of its particles decreases causing its strength to decrease. This way, the peak strength is followed by…
