公路路线方案合理性研究-道路与铁道工程专业毕业论文.docx

摘 要
公路交通的快速发展以及中西部地区山区高速公路的发展对公路设计、施工、管理和养护技术提出了更高的要求,路线的合理性则是其中的首要问题之一。由于山区地形、地质、水文、生态的复杂性和山区高速公路对平、纵线形的高要求,也使路线的合理性研究成为客观需求。本文从公路选线特点和基础理论出发, 提出公路路线合理性的研究课题,研究保障路线合理性的理念、方法和程序等问题,以实现公路交通的可持续发展。
首次系统研究了路线走廊带的选择方法,解决了公路走廊带选择缺乏可操作方法和程序的问题,为路线方案选择的合理性奠定了基础。
系统研究了路线方案选择方法,提出了生态选线和安全选线的原则、步骤、程序和方法,为设计人员在选线过程中合理协调各种影响因素、解决设计主要矛盾提供了有力的工具。
提出将路线方案评价工作划分为勘察规划期和线形设计期两个阶段的思想, 利用基于层次分析法模糊综合评价方法建立了路线方案评价体系。较为全面的反映了影响路线方案确定的各种因素,实现了对路线方案的科学综合评价。

Abstract
The highway traffic fast development as well as the mountainous area of Midwest set a higher request to the highway design,construction,management and maintenance the technology,the route one of也e chief to plexity of mountainous terrain,geology,hydrology,ecology and the mountainous area expressway high requirement for the flat,vertical line shape,make
the rationality of the route study ing the objective demand as article
starts off the route selection characteristic and the basic theory puts forward the rational research topic of highway route,and researches concepts,methods, procedures and so on,supporting line rationality,in order to achieve sustainable development ofroad traffic.
This article lodges the guiding thoughts and design idea ofroute design to suit Our national condition,which are taking the function as the master the security as the core,humanist,reasonably USeS the technical standard,nimbly utilizing the technical specification,harmonizing the relationship of environmental protection, economy and landscaping,guarantees the sustainable development ofhighway provides the methodology level instruction for guaranteed 0111"national highway route design rationality.
Do the systemic research at the first time in choice method in route corridor belt, solved the question lacking the available operating method and the procedure of choice method in road corridor beIt,lay the foundation for the route plan c
