PLATE Load Test

The Plate Load Test basically consists of loading a steel plate placed at the foundationlevel and recording the settlements corresponding to each load increment. The test load is gradually increased till the plate starts to sink at a rapid rate. The total value of load on the plate in such a stage divided by the area of the steel plate gives the value of the ultimate bearing capacity of soil. Theultimate bearing capacity of soil is divided by suitable factor of safety (which varies from 2 to 3) to arrive at the value of safe bearing capacity of soil. For better understanding, this Plate Load Test can be sub-divided into the following heads,
1. Test set-up
2. Testing procedure
3. Interpretation of results
4. Limitations of the test.
