In all civil engineering projects soil shear strength plays an imperative role as it helps to ascertain the ability of soil to resist deformation under enormous amounts of stress. Soil shear strength is a fundamental property that decides the design and safety of building projects like slopes, embankments, retaining walls, etc by knowing the soil stabilisation. Understanding the concept of the shear strength of soil helps civil engineers do the soil analysis properly. We’d like to go through the article to know more about the topic.
Soil shear strength refers to the process of soil strength that is used to withstand deformation in times of shear or tangential stress. This requires cohesion and friction among the particles for better interlocking. The better cohesion and friction indicate high shear strength, which stabilises the soil under stress.
Direct shear testing is important to know the strength of materials like soil under shear stress to resist deformation. ASTM D3080 test is one of the laid standards for plastics and film materials which provides results of soil testing for construction.
The direct shear test involves placing a soil sample in a shear box, which is divided into two halves. A normal load is applied vertically to the sample to simulate the pressure exerted by overlying soil layers. Then, a horizontal force is applied to the upper half of the box to cause the soil to shear along a predefined plane. The test measures the shear resistance of the soil as it deforms under stress. This method is widely used to determine the soil’s shear strength parameters, including cohesion and internal friction angle, which are crucial for construction projects.
Depending upon the project requirements and soil analysis method there are several tests for measuring the soil compaction test. The method usually depends on soil moisture and whether it is sandy soil, clay soil, or some other kind.
According to the Mohr-Coulomb failure criterion (equation 1), the shear strength of soils consists of two components, cohesion (c) and frictional angle (φ), and is also dependent on the normal effective stress (σ’).
τ=c+σ’tanφ – (1)
So understanding the soil shear strength test can help engineers in many ways. Although the process requires a lot of testing and evaluation, it is necessary to know the soil stabilisation. Determining the strength of the soil will help the structures to withstand the pressure and damage in the long run.
