摘要
该文在三角格网法和方格网法的基础上提出了一种新的土方量计算方法——三角格网+方格网法。为了提高精度,针对复杂地形采用了反距离加权插值法和三角形插值法确定边界,并通过工程实例分析了三种土方量计算方法的精度和优缺点,对实际工程中土方量计算有一定的借鉴作用。
Based on the method of triangular grid and grid,a new method of calculating earthwork is proposed.In order to improve the accuracy of calculating earthwork,using the method of anti-distanceweighted interpolation and triangle interpolation to determine borders of complex terrain,and through the actual examples of project,the accuracy,advantages and disadvantages of three methods of earthwork calculation are analyzed,and it will be a reference for the actual earthwork calculation to a certain extent.
