| Abstract: |
| In view of the deficiency of traditional earthwork calculation of channel ,a new method ,which applies cubic spines interpolation to fit the section area function of fill excavation in channel ,and the uses of Romberg integration formula to calculate earthwork volume of channel was proposed based on the characteristic of the MATLAB of formidable mathematical computation and simple language. At the same,the result of calculation indicated that this method is simple ,precise and feasible for designers to refer. |
