A plate load test is a subject test, which can be done to ascertain the ultimate bearing capacity of the soil and the probable settlement under a certain load. This test is quite popular for the choice and design of a shallow foundation.
Advantages of Plate Load Evaluation
The advantages of Plate Load Evaluation are discussed under –
- Being able to understand the base behavior under loading conditions.
- Evaluation of bearing capacity of soil at a particular thickness and forecast of settlement for a certain load.
- The shallow base can be computed considering the allowable bearing capacity, which can be predicted from the plate load test.
- Time and cost-effective.
- Simple to perform.
Limitations of Plate Load Evaluation
For collecting the essential information concerning the design of a shallow foundation, the plate load test is very helpful, but it’s the following limitations.
- The evaluation predicts the behavior of soil situated at a depth less than double the thickness of the diameter of the plate. But in technical condition, the influence zone of a foundation is all up to a far greater depth. You can also check out cbr test
- The plate load test is done for a short period of time, so it can’t predict the payoff for a longer duration, especially for cohesive soil.
- The bearing capability for clayey soil is practically like the bearing capacity obtained from the plate loading test, but in the event of dense aquatic soil, the plate load test provides a conservative price. The actual capacity obtained for dense sandy soil is greater than the results in the plate loading test.
- The settlement for losing sandy soil is usually greater than the settlement signaled by the plate bearing test.
