1、XX大学毕业设计（论文）摘 要本文主要针对新建铁路精伊线塔尔至伊宁东段的初步设计及相关程序设计。设计的具体内容由以下几个部分组成：结合地形、地质条件，在带状等高线地形图上，按初步设计的步骤，选定线路的基本走向，并进行路基设计，包括线路的平面定线、平面设计、纵断面设计、横断面设计、路基土石方计算程序设计、平面坐标计算程序设计、及相关外文科技文献翻译一篇。平面定线过程中，根据坡度的变化定线；平面设计过程中，要注意使直线与曲线相互协调，充分考虑夹直线和缓和曲线长度的要求；纵断面设计中，注意最大坡度、坡段长度、坡段连接与坡度折减等问题，在变坡点处应合理设置竖曲线 ；在平面坐标计算程序设计中，采用For
2、tran语言编制计算程序；在横断面设计过程中，考虑曲线地段路基面加宽等问题。整个设计分几个阶段进行，每一阶段的工作都需要综合考虑、精心设计。设计的前后都要进行必要的比较、检算，符合标准以后，提交有关设计成果，完成设计。关键词： 平面 纵断面 路基 横断面AbstractThe article aims in designing new-built railway preliminarily for JingYi line from Taer to Yiningdong section and relevant programs. The concrete contents of the des
3、ign are as follows : Following the procedures of preliminary design , combine the topography 、geology condition , select the basic trend of the line on the topographic map of belt contour , and start the subgrade design ，including level location、level section design 、profile design 、cross section de
4、sign 、subgrade cubic meter of earth and stone calculation program and design、level coordinate calculation program of line and design、translating a relevant foreign technological bibliography. During the course of level location, follow the gradient changes to locate the line; During the level design
5、, we should take notice to make straight line and curve coordinate each other, considering adequately the length that intermediate straight line and transition curve required ; In profile design , we must pay attention to the maximum grade 、the connection of grade section and compensation of gradien

During the course of level coordinate calculation program and design, use the Fortran Language to program; In the cross section design, consider the problems of broadening subgrade on curve section. The whole design
7、is divided into several stages to conduct. Every stage requires integrated consideration and careful design. The essential comparison and checkout both are required to do before and after designing. When the design conforms to the standard, submit relevant achievements of design, and then finish the design Key Words: Level section 、 Profile 、 Subgrade 、 Cross Section- 2 -
