ESE-033 -Field/In-Situ Vane Shear Test Apparatus (Bore Hole Type)

The Field/In-Situ Vane Shear Test Apparatus (Bore Hole Type) is a specialized tool used to measure the shear strength of cohesive soils directly in the field. This test is essential for assessing the strength and stability of soils at various depths, particularly in geotechnical investigations and construction projects involving foundations, slopes, and embankments. By providing reliable shear strength data, this apparatus helps engineers evaluate soil behavior under load conditions and make informed decisions regarding site preparation and design.

The apparatus consists of a vane, typically made from durable materials like stainless steel, which is attached to a rod that can be inserted into a borehole. The vane is rotated within the soil to measure the resistance to shear as the soil’s shear strength is determined by the torque required to rotate the vane. This procedure helps evaluate the undrained shear strength of the soil at different depths, which is crucial for understanding its stability and load-bearing capacity.

The Bore Hole Type design allows for testing at various depths, making it suitable for a range of site conditions. The test is conducted by inserting the vane into a pre-drilled borehole, where the vane is rotated and the resistance is measured. The results provide valuable insight into the soil’s shear strength, helping engineers assess the need for stabilization techniques or support structures in foundations, retaining walls, and other earthworks.

Widely used in foundation design, slope stability analysis, and site investigations, the Field/In-Situ Vane Shear Test Apparatus (Bore Hole Type) provides quick, reliable, and direct measurements of shear strength in the field. Its simplicity, portability, and accuracy make it an essential tool for geotechnical engineers working in both urban and remote locations.

In summary, this apparatus is an indispensable tool for geotechnical testing, providing crucial data on soil shear strength to ensure the safety and stability of construction projects and infrastructure development.
