Road Earthwork Calculation System (MATLAB)

Overview

This project is a MATLAB-based application developed to calculate earthwork quantities for road construction using survey elevation data. The system enables terrain visualization through contour maps, generates cross-sectional profiles at selected chainages, and computes cut-and-fill volumes to support efficient road design and planning.

Key Features

• Import survey elevation data from CSV files
• Generate contour maps of the survey area
• Plot cross-sectional profiles at any specified chainage
• Calculate cut and fill volumes for road construction
• Visualize terrain variations using interpolation techniques

Application Interface

The application provides an interactive interface to analyze survey data and compute earthwork quantities for road construction. The main components of the interface include:

1. Chainage List Bar – Used to select specific chainages for analysis
2. Show Contour Map – Displays contour maps of the surveyed area
3. Cross-Sectional Profile – Generates ground and formation level profiles at selected chainages
4. Cut and Fill Volume Report – Calculates and reports earthwork quantities
5. Profile Information Panel – Displays formation level, slope, and related parameters
6. Level Data Input – Allows input of survey level data

Input Parameter Description

• D = Distance from center line
