Curve Setting and Alignment in Civil Engineering Quiz

Curves are used to ensure gradual change of direction at the intersection of straight lines, and they are connected to straight lines or tangents by being tangential to them.

Curves in alignment prevent excessive cutting and filling by making the change in alignment gradual and by providing diversions to avoid obstructions on the straight route.

The types of curves mentioned in the text are simple curve, compound curve, reverse curve, transition curve, and lamniscate curve. Each type has its own unique characteristics and purpose in alignment design.

<p>A simple circular curve consists of a single arc connecting two tangents or straights. It is usually represented by the length of its radius or by the degree of curve.</p> Signup and view all the answers

<p>A compound curve consists of two arcs of different radii curving in the same direction and lying on the same side of their common tangent, with their centers being on the same side of the curve. This differs from a simple circular curve, which consists of a single arc connecting two tangents or straights.</p> Signup and view all the answers
