摘　　要：针对传统土石方挖填方法存在操作复杂、工期长、投资高的问题,提出在地形、地貌、岩石类型、地下障碍、原始标高、设计标高和工程地质影响因素下利用三维矿业工程软件(3DMine)优化挖填土石方的4种方法:三角网法、网格法、断面法、区域土方平衡法.通过在工程场地的特定面上设计出两个需要挖填的相交面1.3dm、2.3dm,生成这两个面之间的闭合交线3ds,建立面1.3dm和2.3dm的三维模型,让其三维可视化,分别用三角网法中线分布结构和密度原理,网格法中微积分原理,断面法中条形地带和沿线原理,区域土方平衡法中扩展边坡角和平均松散原理来切割,模拟出挖填土石方三维详细模型,并对挖填土石方进行优化,提高了计算精度,使施工操作简单、工期缩短、投资降低.Aimed at the disadvantages of traditional methods, such as complicated operation, long construction period and high investment, four optimum filling earthwork methods of triangulation, grid, section and regional earthwork balance by 3D mine software（3Dmine） were proposed under the influence of terrain, landform, rock type, underground obstacles, original elevation, design elevation, engineering geology. Firstly, the two intersecting faces of 1.3 dm and 2.3 dm which need to excavate and fill were designed on specific off-site surface, and the closure of intersection line 3 ds between the two faces was generated. Secondly, visual three-dimensional model between face 1. 3 dm and face 2.3 dm was established. Thirdly, the detailed three-dimensional model of excavating and filling earthwork was designed after three-dimensional model was respectively optimized using principle of line distribution structure and density, principles of calculus, principles of strip zone and roads. It improves the calculation accuracy, which increases the three-dimensional effect, simplifies construction process, shortens construction period, and reduces investment.
