铁路高路基设计本科毕业论文设计
57页1、摘 要 在黄土地区修筑高等级铁路,由于黄土特殊的性质和复杂的地质、地理因素,许多路段不可避免地出现了高填的路基。于是高路堤边坡稳定性分析就成了当前面临的主要问题之一。本文通过对西沟门至陈峪段的线路设计,根据铁路路基设计规范,对铁路选线、定线、线路纵横断面设计以及与路基设计有关的一系列附属建筑物进行了设置。讲述了定线的基本原则、铁路路基的特点,根据已有的地形地貌资料、工程地质资料、主要技术指标、线路高程要求等选择合理的线路,确定路基的纵横断面形式及位置,并且绘制了相应的纵横断面设计图。针对特殊地段设置了高路堤,采用圆弧条分法检算其边坡稳定性,对高路堤的施工、排水及其边坡防护进行了详细阐述。由于高路堤占地面积大,故设一悬臂式挡土墙减少土石方施工,并介绍了挡土墙的施工和排水措施。根据实际情况计算土石方量,并对整个线路编写了施工组织设计。关键词:铁路选线;高路堤;边坡稳定性;悬臂式挡土墙Abstract It is inevitablely appears high fill the roadbed to construct the high-grade railway in the loes
2、s areas ,for the Loess special nature and complexity of the geological, geographical factors. So ,how to analysis high embankment on a slope stability become one of the main issues facing at present. Based on the location design of Xi Gou Men to Chen Yu,and according to the railway roadbed design specifications from the railway location, the alignment has to vertical and horizontal lines cross-section design and the design of the embankment buildings were set up. On the alignment of the basic pr
3、inciples of the characteristics of railway roadbed, in accordance with the existing topography, engineering geology, the main technical indicators and line elevation requirements choose reasonable lines, and determine the form and position of vertical and horizontal cross-section. Finally, design the corresponding vertical and horizontal cross-section. Set up a special section for high embankment, and use the arc of the method to calculat its slope stability, the construction of high embankment,
4、it is elaborated the construction of high embankment drainage and slope protection. As the high embankment take a lot of place, it set up a retaining wall to reduce the construction of earth and stone, and gave a briefing on the construction of cantilever retaining wall and drainage measures. Based on the actual terms of earth and stone, designed the entire line of the construction. Key words: railway location; high embankment; slope stability; cantilever retaining wall目 录第一章 概 述1一、铁路路基的特点及建筑要求1
