At PSL, we specialise in conducting accurate and reliable shear box tests, both large and small scale.
These tests are vital in assessing the shear strength and behaviour of soils, helping engineers and geotechnical professionals make informed decisions in various construction and infrastructure projects. With our state-of-the-art equipment and expertise, we deliver comprehensive geotechnical testing solutions to meet your specific requirements.
Shear box tests are commonly used to determine the shear strength parameters of soils, such as cohesion (C) and angle of internal friction (φ). These tests involve applying a controlled force to a soil specimen and measuring its response, allowing for the characterisation of the soil's shear strength and deformation characteristics. By conducting shear box tests, engineers can assess the stability and performance of soil in various applications, including foundation design, slope stability analysis, and embankment construction.
Large Shear Box Tests:
Our advanced laboratory facilities enable us to perform large shear box tests, which are particularly useful for evaluating the behaviour of soils under a range of stress conditions. Large shear boxes allow for testing representative samples, ensuring accurate results for larger-scale geotechnical scenarios. These tests are commonly employed in the analysis of soil for dam construction, retaining walls, and other geotechnical structures subjected to significant loads.
During a large shear box test, a soil specimen is confined within the shear box apparatus, which applies normal stresses and shear forces to the sample. Our experienced technicians meticulously control the loading conditions, ensuring precise and repeatable test results. Through comprehensive data analysis, we provide you with valuable insights into the shear strength, deformation characteristics, and overall behaviour of the soil under consideration.
Small Shear Box Tests:
In addition to large-scale testing, PSL is well equipped to conduct small shear box tests, having 18 on site. These tests are performed on smaller soil specimens and are particularly useful in characterising the behaviour of cohesive soils, such as clays and silts. Small shear box tests provide valuable information about the undrained shear strength and stress-strain behaviour of cohesive soils, enabling accurate assessments of their stability and suitability for construction projects.
During a small shear box test, a carefully prepared soil sample is placed in our smaller shear box apparatus. The specimen is subjected to controlled axial loading, while lateral stresses and shear forces are simultaneously applied. This testing method allows us to determine the soil's shear strength and its response to different loading conditions, aiding in the design of foundations, excavations, and other geotechnical structures where cohesive soils play a significant role.
