Liquidity Index of Soil Solution

STEP 0: Pre-Calculation Summary

Formula Used

Liquidity Index = (Water Content of Soil-Plastic Limit)/Plasticity Index
I_l = (w-W_p)/I_p
This formula uses 4 Variables

Variables Used

Liquidity Index - Liquidity Index is ratio of difference between moisture content and plastic limit to plasticity index.
Water Content of Soil - Water Content of Soil is the natural water content of soil sample.
Plastic Limit - Plastic limit is water content at which soil changes from semi solid to plastic state.
Plasticity Index - Plasticity Index is difference between liquid limit and plastic limit.

STEP 1: Convert Input(s) to Base Unit

Water Content of Soil: 1.79 --> No Conversion Required
Plastic Limit: 1.2 --> No Conversion Required
Plasticity Index: 1.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_l = (w-W_p)/I_p --> (1.79-1.2)/1.2

Evaluating ... ...

I_l = 0.491666666666667

STEP 3: Convert Result to Output's Unit

0.491666666666667 --> No Conversion Required

FINAL ANSWER

0.491666666666667 ≈ 0.491667 <-- Liquidity Index

Angle of Internal Friction for Soil

Go Angle of Internal Friction = arctan(Shear Force on Soil/Normal Force on Soil)

Moisture Content of Soil given Liquidity Index

Go Water Content of Soil = ((Liquidity Index*Plasticity Index)+Plastic Limit)

Plasticity Index of Soil given Liquidity Index

Go Plasticity Index = (Water Content of Soil-Plastic Limit)/Liquidity Index

Liquidity Index of Soil

Go Liquidity Index = (Water Content of Soil-Plastic Limit)/Plasticity Index

Shearing Force on Plane when Sliding on Plane is Impending

Go Shear Force on Soil = (Normal Force on Soil*Coefficient of Internal Friction)

Normal Force on given Plane in Cohesionless Soil

Go Normal Force on Soil = (Shear Force on Soil/Coefficient of Internal Friction)

Coefficient of Internal Friction for Soil

Go Coefficient of Internal Friction = (Shear Force on Soil/Total Normal Force)

Percent of Soil Finer than Clay Size given Activity Index

Go Percentage of Clay Fraction = (Plasticity Index/Activity Index)

Plasticity Index of Soil given Activity Index

Go Plasticity Index = (Activity Index*Percentage of Clay Fraction)

Activity Index of Soil

Go Activity Index = (Plasticity Index/Percentage of Clay Fraction)

Liquidity Index of Soil Formula

Liquidity Index = (Water Content of Soil-Plastic Limit)/Plasticity Index
I_l = (w-W_p)/I_p

What is Liquidity Index of Soil?

The liquidity index (LI) is used for scaling the natural water content of a soil sample to the limits. It can be calculated as a ratio of difference between natural water content, plastic limit, and liquid limit.

How to Calculate Liquidity Index of Soil?

Liquidity Index of Soil calculator uses Liquidity Index = (Water Content of Soil-Plastic Limit)/Plasticity Index to calculate the Liquidity Index, The Liquidity Index of Soil formula is defined as as a ratio of difference between natural water content, plastic limit, and liquid limit. Liquidity Index is denoted by I_l symbol.

How to calculate Liquidity Index of Soil using this online calculator? To use this online calculator for Liquidity Index of Soil, enter Water Content of Soil (w), Plastic Limit (W_p) & Plasticity Index (I_p) and hit the calculate button. Here is how the Liquidity Index of Soil calculation can be explained with given input values -> 0.491667 = (1.79-1.2)/1.2.

FAQ

What is Liquidity Index of Soil?

The Liquidity Index of Soil formula is defined as as a ratio of difference between natural water content, plastic limit, and liquid limit and is represented as I_l = (w-W_p)/I_p or Liquidity Index = (Water Content of Soil-Plastic Limit)/Plasticity Index. Water Content of Soil is the natural water content of soil sample, Plastic limit is water content at which soil changes from semi solid to plastic state & Plasticity Index is difference between liquid limit and plastic limit.
