Plate load test

i havent written much matter instead i have kept pictures

1. PLATE LOAD TEST BY : SWETHA SHA JAIN

2. INTRODUCTION : Plate Load Test  is a field test for determining the  ultimate bearing capacity of soil  and the likely settlement under a given load Total value of load on plate divided by the area of the steel plate gives the value of ultimate bearing capacity

3. Its subdivided into following steps : * Test setup * Testing procedure * Interpretation of results * Limitation of the test

4. Test setup:

5. Testing procedure: The test can be done by two methods .they are : *gravity method *truss method

6. Interpretation of results:

7. Limitations of plate load test : The test results reflect only the character of the soil located within a depth of less than twice the width of bearing plate The  Plate Load Test  being of short duration, does not give the ultimate settlements particularly in case of cohesive soils. For clayey soils the bearing capacity (from shear consideration) for a large foundation, is almost same as that for the smaller test plate. In dense sandy soils the bearing apacity increases with the size of the foundation and hence the test with smaller size test plate tends to give conservative values in dense sandy soils.
