| Abstract: |
| Based on the analysis of features of twist surface, parametric equation of twist surface was creatively derived by using vector law, At the same time, aiming at the deficiency of traditional earthwork calculation, an accurate formula for the calculation of earthwork with original twist surface was provided, also, this paper demonstrated the application of this formula and error analysis. The result indicates that it is of little error, high accuracy and universal application. |
| Key words: twist surface earthwork calculation vector law parametric equation |
