摘要
针对施工区域地形条件复杂、设计标高需按施工情况实时进行调整等问题,讨论如何建立内外边界约束条件下的Delaunay三角网,研究顾及就近取弃土量、填挖平衡、土质可松性等因素的土方均衡计算方法,并结合实例进行分析与比较,具有一定的参考价值。
To deal with the problems that the terrain conditions of construction area are complex and it needs to adjust the design elevation according to the construction conditions,a method of achieving the earthwork balance is researched considering factors of fetched or abandoned earthwork nearby,balance in cut and fill,relaxed soil,which based on the delaunay triangulated irregular network with boundary constraint.In addition,the method is analyzed and compared through an example of project and it will be a reference to a certain extent.
