毕设基本摘要
摘 要
随的着社会经济发展，公路起着越来越重要的作用。本文主要讲述了公路设计中的一个完整的过程。本设计主要是一阶段设计：初步设计阶段。
首先，讨论道路修建的可行性，从地形，地质，气象，水文条件等自然因素和交通量的增长情况来论述该公路修建的可行性与必要性，为道路修建进行理论研究。
其次，本着合理利用当地资源，综合考虑地形，地质，水文气象条件等自然因素和当前交通量以及交通量增长情况来确定公路等级，并根据公路等级来确定道路设计中的技术指标。
本文着重介绍了广西三级公路设计的基本情况，以及道路设计的基本流程。首先结合当地的一些基本情况，从交通量分析入手，确定拟建道路的等级。然后依次进行道路线形设计、平面设计、纵断面设计、横断面设计，还有路基路面设计、防排水工程设计、防护工程设计等。最后进行了工程预算设计，翻译了相当数量的专业外文资料。
关键词：三级公路设计，交通量，工程预算，路基设计，路面设计
ABSTRACT
As the development with the social economy, the highway plays more and more important role. This design contains the whole stage in the designing course .
First of all, discussing the feasibility building in road, at topograph, and the growth situations of volume of traffic come and expoud the fact this feasibility and necessity who highway build meteorological hydrology terms, etc. natural factorses geology. Build the theoretical hydrology research for the road.
Secondly, in line with utilizing local resources rationally, Consider and at present and volume of traffic increase traffic situation come and determine highway grade topographies, geologies, hydrometorological termeseses natural factors.
This text has introduced the basic situation of the design of guagnxi Class Ⅲ highway, the basic procedure of and the design of road emphatically. Combine some local basic situations at first , is analysed and starts with from the volume of traffic, confirm that plans to build the grade of the road. Then carry on the line shape design of the road , planar design , vertical section design , cross section to design sequentially, there is road bed road surface to design , defend draining off water engineering design , protecting engineering design ,etc.. Carried on the project budget to design finally, translated a great deal of specialized foreign language materials.
KEYWORDS: the design of ClassⅢhighway, volume of traffic, project budget, road bed design, pavement design
