摘要
基于MATLAB强大的数学计算功能与友好的界面,针对现有渠道渐变体工程土方量计算方法的不足,提供了用三次样条函数拟合断面面积函数,再运用复化梯形求积公式计算土方量的新方法;并用实例说明了该方法的应用及其误差分析。结果表明,该方法计算过程简单、计算误差小,可供设计、施工人员参考。
Based on MATLAB, which has exoellent function of mathematics calculation and friendly interface, this study aimed at the shortage of the current calculation of canal transition earlhwork volume and provided a new method by using cubic spline function,sectional area function and compund trapezoid fomula to calculate earth volume.In addition,it set an example to illustrate the application and error analysis of this method,which shows a simpler computational pwcess and smaller computational error.
