Question

Explain how you would related the terms plasticity index

and liquidity index in practical geotechnical engineering situation?

Answer 1

*Plasticity index and liquidity index are the geotechnical properties. these properties indicate us the cohessive property of the soil. liquid limit helps us in idendifying the physical state of the soil and consistency of soil.

these valuses helps in correlating with soil property and gives us idea about the design.

these are determined by the laboratory tests.

relation between liquidity index and pasticity index is given by

LI=(W-PL)/Ip

LI-LIQUIDITY INDEX

W-WATER CONTENT

PL-PLASTIC LIMIT

Ip-PLASTICITY INDEX
