Total Volume in Soil Mechanics is defined as the total capacity of the soil mass, including both solids and voids. It is a fundamental parameter in geotechnical engineering for analyzing soil properties and behavior.
The calculator uses the formula:
Where:
Explanation: This formula calculates the total volume of soil by relating the unit weight of solids, volume of solids, and dry unit weight of the soil mass.
Details: Accurate calculation of total volume is essential for determining soil density, porosity, void ratio, and other critical geotechnical parameters that influence soil stability and foundation design.
Tips: Enter unit weight of solids in N/m³, volume of solids in m³, and dry unit weight in N/m³. All values must be positive numbers greater than zero.
Q1: What is the difference between total volume and volume of solids?
A: Total volume includes both solid particles and void spaces, while volume of solids refers only to the space occupied by the solid particles themselves.
Q2: How does dry unit weight differ from unit weight of solids?
A: Unit weight of solids is the weight per unit volume of solid particles only, while dry unit weight is the weight of solids per unit total volume of soil mass.
Q3: What are typical values for unit weight of solids?
A: For most soils, unit weight of solids ranges from 25,000 to 27,000 N/m³, with common minerals like quartz having values around 26,500 N/m³.
Q4: When is this calculation most useful?
A: This calculation is particularly useful in soil compaction studies, foundation design, and slope stability analysis where accurate volume measurements are critical.
Q5: Are there limitations to this formula?
A: This formula assumes homogeneous soil composition and may need adjustment for soils with significant organic content or unusual mineral compositions.
