Plate Load Test

Plate Load Test Plate Load Test is a field test for determining the ultimate bearing capacity of soil and the likely settlement under a given load The Plate Load Test basically consists of loading a steel plate placed at the foundation level 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

Bearing capacity

In geotechnical engineering bearing capacity is the capacity of soil to support the loads applied to the ground The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil Ultimate bearing capacity is the theoretical maximum pressure which can be supported without failure allowable bearing
