| 摘 要： | 针对现有扭面工程土方量计算的不足，基于MATLAB的强大数学计算功能与友好界面，提出用三次样条函数拟合断面面积函数，运用复合梯形求积公式计算土石方量的新方法，并用实例说明了该方法的应用，结果表明计算过程简单、误差小，可供设计人员参考。 |

| Abstract: | Aiming at the deficiency of earthwork calculation of twist surface, based on the function and interface of MATLAB, a new method is put forward that use cubic spline spaces fitting cross-section area function,and adopt composite-trapezoid integral formula to calculate earthwork with example, the result shows that the calculation is simple and has small error, which can be taken as reference for the designers. |
| Keywords: | cubic spline spaces twist surface earthwork calculation application |
