摘要
本设计是根据设计任务书的要求及其公路桥梁的相关规范的规定，对XX级公路综合设计进行方案必选、平面主线设计、纵断面设计、横断面设计、路面结构设计及桥梁设计，并进行计算绘图。本设计公路等级为一级，设计车速100km/h，双向六车道。
设计中主要包括以下几个阶段：
1、选线：XX一级公路综合设计K0+000～K4+347.913，根据其走向，从地形图上另选一条线路，考虑尽量不占或少占经济田和少拆迁的选线原则，并且进行了方案的比选。设计线形满足规范要求。
2、主线平面设计：全线长4347.913米，在这段路上选了三个交点，交点半径分别为750m、800m、1200m.
3、纵断面设计：考虑满足排水的最小纵坡要求进行了路线纵断面设计。全线共有三个变坡点，半径分别为12000m、25000m、55000m；
4、横断面设计：以桩号为基本点，进行了横断面设计、路基设计表设计、土石方计算、排水平面设计等。
5、路面结构设计：采用手工和程序相结合的办法进行了路面结构设计。
6、预算：编制了路线范围内路基和路面部分的预算文件。
7、桥梁设计：主要进行了桥梁上部结构和配筋的计算和验算。
大部分图纸使用CAD绘制，部分数据使用EXCEL计算。
关键词：主线平面设计、纵断面、横断面、路面结构设计、施工组织设计、报价计算设计、桥梁设计。
Abstract
This design is according to the design project description request and the highway bridge related standard stipulation,Shen Liao to design a comprehensive program of road will be elected、the longitudinal section design,the cross section design,the pavement structure design and the bridge design,and carries on the computation cartography.This design highway classification for first-level,design vehicle speed 100km/h,two-way six lanes.
In the design mainly includes the following several stages:
1、Route selection:Liaoning Shenyang highway level integrated design K0+000～K4+347.913,according to its trend,Chooses a line in addition from the topographic diagram,considered that does not occupy or little occupies the route selection principle which as far as possible economy Tian Heshao relocate,and carried on the plan ratio to elect.Designs linear satisfies the code requirement.
2、Master line plane design:4.347.913km long line in this election,three points on the road,intersection radius of 750m,800m,1200m.
3、Longitudinal section design:Considered that satisfied draining water the smallest lengthwise grade request to carry on the route longitudinal section design.The entire line altogether has three changes the slope spot,Radius of 12000m,25000m,55000m;
4、Cross section design:Take the station number as the fundamental point,has carried on the cross section design,the grade location table design,the cubic meter of earth and stone computation,the draining water plane design and so on.
5、Pavement structure design:Uses the means which the handwork and the procedure unify to carry on the pavement structure design.
6、Budget:Has established in the hole scope the roadbed and the road surface part budget document.
7、Bridge design:Mainly has carried on the bridge superstructure and the reinforcing bars computation and the checking calculation.
The majority of blueprints use the CAD plan,the partial data use EXCEL to calculate.
Key word:Master line plane design,longitudinal section,cross section,pavement structure design,Construction of organizational design,pricing calculation of designbridge design.
