PLATE BEARING TEST AZA0929

Description

Principle of Plate Bearing Test

The Plate Bearing Test involves applying a static load incrementally on a rigid steel plate placed at foundation level and measuring the corresponding settlement. The resulting load–settlement curve is used to determine:

• Ultimate bearing capacity of soil

• Safe bearing pressure

• Settlement behavior under working loads

• Modulus of subgrade reaction (k-value) for pavement design

The AZA0929 system enables accurate execution of this test in accordance with Indian and international standards.

System Components and Working Method

Loading System

• High-capacity hydraulic jack operated via a manual hand pump

• Load applied gradually in defined increments

• Load measurement via calibrated pressure gauge or optional digital load cell

Reaction System (arranged by user)

• Kentledge (concrete blocks / steel weights), or

• Reaction frame with anchors / piles

• Reaction load ≥ 1.5 × maximum test load (as per IS 1888)

Bearing Plates

• Rigid machined steel plates

• Circular plates ensure uniform stress distribution

• Multiple diameters available for different test requirements

Settlement Measurement

• 3 or 4 high-precision dial gauges mounted symmetrically

• Readings taken against an independent rigid reference beam (datum bar)

• Optional LVDT sensors with digital data logger for advanced monitoring
