The Survey Curve Calculator is a valuable tool used in civil engineering to determine essential parameters for designing curved paths or roads. It helps calculate the radius of the curve and the deflection angle based on specific inputs. This article aims to delve into the functionality, formulas, examples, and frequently asked questions related to this tool.
Formulas Used in Survey Curve Calculator
Radius of the Curve (R):
The formula to calculate the radius of the curve is:
R =(T2 / 8L)+ (L / 2) Where:
- R represents the radius of the curve.
- L is the length of the curve.
- T denotes the tangent distance, which signifies the distance between the two straight lines that the curve connects.
Deflection Angle (θ):
The formula for determining the deflection angle in degrees is: θ = 360L / 2πR
Here:
- θ signifies the deflection angle in degrees.
These formulas are crucial in civil engineering for planning and executing curved structures with precision.
