Plate Load Test
Plate Load Test
The plate load test is a field test used to determine the bearing capacity and settlement characteristics of soil beneath a proposed structure’s foundation. This test is mostly used for foundation design, research and development projects, and quality assurance of works.
Test Procedure
A circular steel plate, typically ranging from 0.3 to 1.0 meters in diameter, is selected based on the specific requirements of the project. The plate is usually equipped with load cells or hydraulic jacks to apply and measure the load. The test location is cleared of any debris or vegetation, and the ground surface is levelled.
A shallow pit is excavated to accommodate the plate, ensuring that it rests directly on the undisturbed soil. Incremental loads are applied to the plate using hydraulic jacks or a loading frame. The load is increased gradually in predetermined increments until the desired maximum load or failure point is reached.
Test Outcomes
During loading, settlement measurements are taken at regular intervals using dial gauges or electronic displacement transducers. These measurements are used to calculate the settlement of the soil beneath the plate.
Load versus settlement data is recorded throughout the test, allowing engineers to analyze the soil’s load-bearing capacity (The ultimate bearing capacity of the soil can be determined by dividing the maximum applied load by the contact area of the plate) and settlement behaviour (The settlement data obtained during the test is analyzed to assess the soil’s compressibility and its ability to support the anticipated loads from the structure).
