Generally, there is a sneaky correlation used to give an indication of bearing capacity in cohesive/clay soils. This is SPT X 10 = Bearing Capacity. Webformula undrained shear strength is found outwithout conducting any laboratory test. A graph was plotted between SPT N and the undrained shear strength (Cu) and the correlation that is obtained and it is compared with previous correlations.[8] Table 3: Calculating undrained shear strength LI (%) Cu (kPa) 0.61 10 0.31 40 0.41 25 0.13 92 control and ownership sociology
