In order to provide a simple and convenient method of earthwork volume calculation in the work of terracing the land on hillside,a formula for earthwork volume calculation was developed using the methods of literature consultation and geometrical mathematic calculation. The result showed that the earthwork volume is proportional to the inclination of field surface before terracing,inversely proportional to the inclination of field surface after terracing and proportional to the elevation difference between two adjacent field surfaces.
