Plate load testing
In-situ testing with rigid steel plates to determine soil’s ultimate bearing capacity and settlement behavior. The Plate Load Test is a field test to determine the bearing capacity and settlement characteristics of soil under a given load. It is widely used for designing foundations of buildings, bridges, and pavements. Load vs. Settlement Curve was Plotted to assess soil behavior.
- Loading Plate: Usually a steel plate, square or circular, with sizes typically 300 mm × 300 mm, 450 mm × 450 mm, or 600 mm × 600 mm for shallow foundations was used.
- Reaction System:Jack (hydraulic or screw type) to apply load. Reaction beams or anchors (steel rods, dead weights) to resist the load. The required load for the test was applied to the plate resting on the soil sample using a hydraulic jack, and the applied load was measured with the help of a load cell equipped with an indicator.
- Dial Gauges or Settlement Measuring Devices: Two dial gauges were used to measure the settlements occurring during the test. Each dial gauge had a least count of 0.02 mm and a measuring capacity of 50 mm.
In SoilGlobe Engineering Pvt. Ltd., we conduct Plate Load Tests in strict compliance with IS 1888 and other international standards. With modern hydraulic systems, precise settlement gauges, and experienced geotechnical engineers.
Purpose of Plate Load Test
- To evaluate the safe bearing capacity (SBC) of soil.
- To determine the modulus of subgrade reaction (k-value).
- To study the load–settlement characteristics of soil under field conditions.
- To provide direct input for the design of foundations, pavements, and embankments.
