摘要
在本设计中，主要是进行二级公路设计。设计部分的公路全长2717m，设计车速80km/h，双向四车道，设置中央分隔带。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，包括了平面设计、纵断面设计、横断面设计、平纵组合设计和土石方计算与调配。接着对路基进行了设计:布置路基横断面，并对路基的排水、防护和特殊路基进行了设计。接着又对路面进行了设计:对道路行车进行了轴载换算后设计了路面结构，并进行了应力验算。设计最后对桥梁涌洞、环境保护进行了简单设计

Abstract
This design primarily focuses on the construction of the Rongchang to Panlong highway.The design section of the highway spans a total length of 2717 meters,with a design speed of 80 km/h.It consists of a four-lane two-way road with a central median strip.Initially,various design materials and basis were compiled,and a study was conducted on the natural conditions along the route,design technical standards,and key economic and technical indicators.Following this,route design was undertaken,encompassing horizontal design,longitudinal profile design,cross-sectional design,combined horizontal and vertical alignment design,and earthwork and stonework calculation and allocation.Subsequently,the design of the roadbed was carried out:the cross-section of the roadbed was arranged,and the drainage,protection,and special roadbed were designed accordingly.Then,the pavement design was conducted:after converting the axle load of road traffic,the pavement structure was designed,and stress checks were performed.Finally,a brief design of bridges,tunnels,and environmental protection measures was included.
