摘要

本文主要针对新建铁路精伊线莫仁至阿恰勒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，注意紧坡地段和缓坡地段的定线要求及定线技巧，在设计过程中，由于两站之间有较大的高程差，所以为了减少挖方量和争取最大高程，线路采用较大的坡度上坡，并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，对两种方法进行比较，采用Fortran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：平面纵断面竖曲线路基横断面

Abstract

The article aims in designing new-built railway preliminarily for JingYi line from Moren to Aqiale section and relevant programs.

The concrete contents of the design 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、cro section design、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; pays attention to the tight slope land sector and the gentle slope land sector decides the line request and decides the line skill, in design proce between, because two stands has a bigger elevation difference, therefore in order to reduce the volume of excavation the quantity and strives for the maximum elevation, the line uses an greater slope uphill, and the attention causes the straight line and the curveinter coordination, the full consideration clamps the straight line to be gentle and the length of curve request; In profile design , we must pay attention to the maximum grade、the connection of grade section and compensation of gradient etc; On the grade change point, we should dispose the vertical curve reasonably .During the course of level coordinate calculation program and design, compare thee two methods and use the C Language to program; In the cro section design, consider the problems of broadening subgrade on curve section.

The whole design is divided into several stages to conduct.Every stage requires integrated consideration and careful design.The eential 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、Vertical curve、Subgrade、Cro Section- 2 -
