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
10. Limitations of plate load test :
โ The test results reflect only the character of the soil located within a depth of
less than twice the width of bearing plate
โ The Plate LoadTest being of short duration, does not give the ultimate
settlements particularly in case of cohesive soils.
โ For clayey soils the bearing capacity (from shear consideration) for a large
foundation, is almost same as that for the smaller test plate.
โ 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.
