摘　　要：本文是根据数字地形模型原理,将地形模型数字化,得出各象点的 X、Y、Z值.在计算机控制的立体坐标量测仪上进行数据测试,并绘制成图,用于铁路纵断面的优化设计.In accordance with the principle of the digitized topographical model,The paper describes how the computer-controthed three-dimensional digitalizer is assemble, how the topographical data is digitalized and how the drowings,Come into leing and this paper described the aboption of gradient-projeetion methed in the optimum design of railway profiles with the use of the three-dimensional digitalizer.

关 键 词：数字 地形 模型 铁路 设计 数模
