Plate load test is to find the bearing capacity and the settlement of the foundation.
Description:: a test plate, square or circular in shape, are used. The plate is placed at the proposed level of the foundation and is subjected to incremental loading. Settlement at each increment of the loading is measured and a load-settlement curve is plotted. Bearing capacity and the settlement of the foundation are determined from the load-settlement curves.
Bearing capacity of soil
load bearing capacity
15.00 mt/ sq m
Generally it is called as SBC ( safe bearing capacity).It indicates how much load the substrata can bear without settlement. its unit is Metric tonnes per square meter T/sqm.
field capacity is the quantity of water that is retained by a soil after drainage by cohesion and adhesion.
it is measure in p.s.i. ( presure / square inch) to see if the compounds will with-stand an amount of presure over a lenght of time in order to determine satisfatory use of material or change it
Bearing capacity of soil
Bearing capacity is the ability of the underlying soil to support the foundation loads without shear failure. Bearing capacity factors are empirically derived factors used in a bearing capacity equation that usually correlates with the angle of internal friction of the soil.
Bearing capacity of soil= Load carried by soil / unit Area Definition : The safly retained capacity by soil is termed as SBC(Safe Bearing Capacity) of soil. While you design a footing , it is the main factor to consider . To calculate the area of footing Area of footing = load/ SBC
Yes, it can improve the bearing capacity but the extent has to be seen with other conditions like soil, mode of filling, treatment given. In fact this was done in delhi to counter site conditions.
load bearing capacity
The the bearing capacity of silt soil can be improved by:Compacting the soil to increase it's density.Increasing the depth of the foundation layer as the increased effective stress will act to increase bearing capacityThe use of geosynthetics may act to increase bearing capacityThe use of lime stabilisation / soil mixing techniques may also act to increase the bearing capacity of silt.
bearing capacity is the capacity of soil or strata that can be able to sustain the load of superstructure in the unit of load per m2 either ton/m2 or KN/m2 bearing pressure is nothing but bearing capacity example when you apply 100 KN on a unit area, equal opposite pressure will rise from the soil. load / area = bearing capacity
The link between CBR and bearing capacity if you get figures in CBR how can you link them to the bearing capacity in kPa, this is the link in soil testing.
The bearing capacity of slit soil with geogrid will be improved with the direct application of geogrid. However, the application of geocell or geocell/geo slurry mixture between the two layers of geo crumb will bring better results. If the slit soil is very weak due to the softness, then the application of geogrid to the existing soil will improve the bearing capacity of the soil. Also, the application of geogrid initially may improve the bearing capacity of the soil, but your effort will be diverted when the soil becomes dry and when the soil is loaded or the internal friction angle of the soil is reduced.
SBC is the safe bearing capacity of a soil, beyond this value if soil is loaded, it will fail to bear the load applied on it and will fail. Its value can be found out by standard penetration test, plate load test or cone penetration test.
SPT n Values can help to calculate the Bearing Capacity of any soil specimen as they will combine to change the density of the soil by extracting various chemicals such as helium and hydrogen.
