摘　　要：论述了利用断面法和Delaunay三角网法计算场地平整土方量的2种算法思想,重点论述了利用Delaunay三角网中的三角形计算土方的算法思想。首先根据Delaunay三角网中每个三角形3个顶点的高程判断此三角形区域是填方、挖方还是填挖方都有。然后根据情况利用合适算法计算三角形区域填挖方量。最后利用Java 3D语言编程开发了场地平整土方计算小软件,结合实例计算证明此软件所涉及的算法正确,有效。The paper discusses the thought of the two algorithms for calculation of earthwork in site leveling with the section method and the Delaunay triangulation method,and mainly focuses on the triangle in Delaunay triangulation algorithm to calculate earthwork.First of all,according to the elevation of the three vertices of each triangle in the Delaunay triangulation,it is to determine filling,cutting or the joint of filling and cutting in this triangle area.Then,the appropriate algorithm is adopted to calculate the filling-cut volume in the triangle area.Finally,small software for calculation of earthwork in site leveling is developed with Java 3D programming language.The cases confirmed that the algorithm used in this software is correct and effective.
