Mean Sectional Area Method Solution

Follow our step by step solution on how to calculate Mean Sectional Area Method?

FIRST Step Consider the formula

V earthwork = L section \cdot \frac{(B \cdot d 1) + (S \cdot {d 1}^{2}) + (B \cdot d 2) + (S \cdot {d 2}^{2})}{2}

Next Step Substitute values of Variables

∴

V earthwork = 20000mm \cdot \frac{(10000mm \cdot 1201mm) + (2 \cdot {1201mm}^{2}) + (10000mm \cdot 1600mm) + (2 \cdot {1600mm}^{2})}{2}

Next Step Convert Units

∴

V earthwork = 20m \cdot \frac{(10m \cdot 1.201m) + (2 \cdot {1.201m}^{2}) + (10m \cdot 1.6m) + (2 \cdot {1.6m}^{2})}{2}

Next Step Prepare to Evaluate

∴

V earthwork = 20 \cdot \frac{(10 \cdot 1.201) + (2 \cdot {1.201}^{2}) + (10 \cdot 1.6) + (2 \cdot {1.6}^{2})}{2}

Next Step Evaluate

∴

V earthwork = 360.14802m³

LAST Step Rounding Answer

∴

V earthwork = 360.148m³

How to Evaluate Mean Sectional Area Method?

Mean Sectional Area Method evaluator uses Volume of Earthwork = Length of Road Section*((Width of Formation Level*Height of Bank at Start Portion of Embankment)+(Side Slope*Height of Bank at Start Portion of Embankment^2)+(Width of Formation Level*Height of Bank at End Portion of Embankment)+(Side Slope*Height of Bank at End Portion of Embankment^2))/2 to evaluate the Volume of Earthwork, The Mean Sectional Area Method formula is defined as calculating the volume of earthwork by taking a mean of those sectional areas, and finally, we multiply obtained mean sectional area by length of road section to get total volume of earthwork. Volume of Earthwork is denoted by V_earthwork symbol.

How to evaluate Mean Sectional Area Method using this online evaluator? To use this online evaluator for Mean Sectional Area Method, enter Length of Road Section (L_section), Width of Formation Level (B), Height of Bank at Start Portion of Embankment (d₁), Side Slope (S) & Height of Bank at End Portion of Embankment (d₂) and hit the calculate button.

FAQs on Mean Sectional Area Method

What is the formula to find Mean Sectional Area Method?

The formula of Mean Sectional Area Method is expressed as Volume of Earthwork = Length of Road Section*((Width of Formation Level*Height of Bank at Start Portion of Embankment)+(Side Slope*Height of Bank at Start Portion of Embankment^2)+(Width of Formation Level*Height of Bank at End Portion of Embankment)+(Side Slope*Height of Bank at End Portion of Embankment^2))/2. Here is an example- 360 = 20*((10*1.201)+(2*1.201^2)+(10*1.6)+(2*1.6^2))/2.

How to calculate Mean Sectional Area Method?

With Length of Road Section (L_section), Width of Formation Level (B), Height of Bank at Start Portion of Embankment (d₁), Side Slope (S) & Height of Bank at End Portion of Embankment (d₂) we can find Mean Sectional Area Method using the formula - Volume of Earthwork = Length of Road Section*((Width of Formation Level*Height of Bank at Start Portion of Embankment)+(Side Slope*Height of Bank at Start Portion of Embankment^2)+(Width of Formation Level*Height of Bank at End Portion of Embankment)+(Side Slope*Height of Bank at End Portion of Embankment^2))/2.
