摘要
本设计是对一级公路段(KO+000~K4+500)进行的道路工程设计。路基设计宽度为24.5m，双向四车道一级公路。本设计先整理了各种设计资料和依据，对沿线自然条件、设计技术标准和主要经济技术指标进行了研究然后进行了路线设计，包括平面设计、纵断面设计、横断面设计、平级组合设计和土石方计算与调配。接着对路基进行设计:布置路基横断面，并对路基的排水防护、挡土墙进行了设计。再就是对路面进行了设计:对道路行车进行了轴载换算后进行了路面结构设计，并进行了应力验算

Abstract
This design involves the road engineering of a first-class highway section(KO+000~K4+500).The design width of the roadbed is 24.5m,featuring a two-way four-lane first-class highway.This design first compiles various design materials and basis,conducts a study on the natural conditions along the route,design technical standards,and major economic and technical indicators,and then proceeds with route design,including horizontal design,longitudinal profile design,cross-sectional design,combination design of horizontal and vertical alignments,and earthwork and stonework calculation and allocation.Subsequently,the design of the roadbed is conducted:arranging the cross-section of the roadbed,and designing the drainage protection and retaining wall of the roadbed.Following that,the pavement design is undertaken:after converting the axle load of the road traffic,the pavement structure design is carried out,and stress checking is performed.
Keywords:First-class Highway;Route Selection and Design;Roadbed;Pavement;Retaining Wall
