In surveying, curves are geometrical shapes that connect straight segments in construction projects. They are regular bends that are used in roads, railways, and canals to gradually change direction. Curves are also used in the vertical plane to avoid abrupt changes in grade.
There are two main types of curves used in surveying: Horizontal curves: Used to transition smoothly between straight sections of a road or railway Vertical curves: Used to provide a gradual change in elevation along the alignment
A compound curve is a type of curve that consists of two or more circular curves connected end to end with different radii and centers. Compound curves are used when a more gradual transition between straight sections is required. A reverse curve is another type of curve that consists of two simple curves joined together but curving in opposite directions.
