| Abstract: | The formation of the surface of the side slope of roads, banks, canals and dams and the method of construction of the side slope's contours are discussed. Based on building the parameter equation of envelope of family of radius_varied circles, the frequently used parameter equation of the side slope of the taper's top moving along column helix, horizontal arc and line is built. The equation can be used to construct the side slope's contour and gradient line correctly. The mathematical model provides a correct, convenient mathematical model which can be applied to digital design for the design of the side slope of roads, banks, canals and dams. |
