Mean Sectional Area Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

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
V_earthwork = L_section*((B*d₁)+(S*d₁^2)+(B*d₂)+(S*d₂^2))/2
This formula uses 6 Variables

Variables Used

Volume of Earthwork - (Measured in Cubic Meter) - Volume of Earthwork is measured in cubic meters without any allowance for an increase in bulk.
Length of Road Section - (Measured in Meter) - Length of Road Section is the total extent /stretch of the road.
Width of Formation Level - (Measured in Meter) - Width of Formation Level or roadway is the sum of the width of the pavement or carriageway including the separators if any and the shoulders.
Height of Bank at Start Portion of Embankment - (Measured in Meter) - Height of Bank at Start Portion of Embankment is the maximum distance between parallel sides of the c/s of the start portion of the embankment.
Side Slope - Side Slope is the graded area immediately adjacent to the graded roadway shoulder. Side slopes are provided on embankments and fill to provide stability for earthworks.
Height of Bank at End Portion of Embankment - (Measured in Meter) - Height of Bank at End Portion of Embankment is the maximum distance between parallel sides of the c/s of the end portion of the embankment.

STEP 1: Convert Input(s) to Base Unit

Length of Road Section: 20000 Millimeter --> 20 Meter (Check conversion here)
Width of Formation Level: 10000 Millimeter --> 10 Meter (Check conversion here)
Height of Bank at Start Portion of Embankment: 1201 Millimeter --> 1.201 Meter (Check conversion here)
Side Slope: 2 --> No Conversion Required
Height of Bank at End Portion of Embankment: 1600 Millimeter --> 1.6 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_earthwork = L_section*((B*d₁)+(S*d₁^2)+(B*d₂)+(S*d₂^2))/2 --> 20*((10*1.201)+(2*1.201^2)+(10*1.6)+(2*1.6^2))/2

Evaluating ... ...

V_earthwork = 360.14802

STEP 3: Convert Result to Output's Unit

360.14802 Cubic Meter --> No Conversion Required

FINAL ANSWER

360.14802 ≈ 360.148 Cubic Meter <-- Volume of Earthwork

How is the calculation of Earthwork in Road Longitudinal Section done?

For the calculation of earthwork in a longitudinal section and cross-section of the ground are taken and the formation line is fixed. The formation line is fixed in consideration of flood level, gradient, height of bank, depth of cutting etc. But for estimating of earthwork this point of utilizing excavated earth from cutting in certain length in banking of the adjacent length may not be taken into account to avoid complicacy.

About Mean-Sectional Area Method

This formula comes under the domain of earthwork quantity estimation for roadwork/embankment.
It deals with the concept that the means of c/s area at different intervals is to be found and then multiplied by the total length of the embankment.

How to Calculate Mean Sectional Area Method?

Mean Sectional Area Method calculator 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 calculate 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 calculate Mean Sectional Area Method using this online calculator? To use this online calculator 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. Here is how the Mean Sectional Area Method calculation can be explained with given input values -> 360 = 20*((10*1.201)+(2*1.201^2)+(10*1.6)+(2*1.6^2))/2.
