黄松甸至敦化二级公路施工图设计

(K136+500－K138+600)

摘 要

本设计是从吉林省中部平原向东部山区的过渡区域（华夏系第二隆起带）二级公路施工图设计。第一步是路线设计，其中包括：平面设计（平曲线的设计计算）、纵断面设计（竖曲线的设计计算）、横断面设计（路基宽度、边沟、车道、边沟等设计），设计成果有平面图、纵断面图、横断面图、直曲线转角一览表、路基设计表、土石方计算表等；第二步是路基路面设计，其中路基的设计包括：路基宽度设计、路基横断面形式设计。路面采用沥青路面，其设计成果包括：路面的结构设计、标准轴载的换算、设计完成的计算、各层材料的容许弯拉应力的计算、弯拉应力的验算等，设计成果有路面结构图、轴载换算表等。

The Secondary Roads Construction Design

of Huang Song Dian to Dun Hua

(K136+500－K138+600)

ABSTRACT

This design is from the Central Plains to the transition region of Jilin Province in

eastern mountain area(Department of the Chinese second uplift)two highway construction drawing design.The first step is to route design,including:Graphic Design(design and calculation of horizontal curve),vertical section design(design and calculation of vertical curve),cross-sectional design(design roadbed width,side ditch,ditch lane,etc.),the design result swith plan,vertical section,transverse plane figure,straight curve angle table,table,design of the Subgrade Earthwork Calculation Table;the second step is the design of roadbed and road surface,wherein the roadbed design includes:width of road bed design,subgrade cross section design.Pavement with asphalt pavement,the design results include: the pavement structure design,the standard axle load conversion,design calculation,each layer of material allowable bending stress calculation,bending stress checking,design results of pavement structure,axle load conversion table.
