西商高速公路C11合同段施工图设计
摘要:西安至商州高速公路C11合同段路段地形为山岭重丘区。通过交通量统计资料的计算,结合工程量、地质条件、筑路材料等诸多因素的考虑,确定设计车速80km/h,,采用沥青混凝土路面进行设计。设计内容包括三维空间设计(平面设计、纵断面设计、横断面设计),路面结构设计(沥青混凝土路面)、防护工程设计(挡土墙等)、排水设施设计。平面设计内容包括公路路线的选择、平面线形的绘制、曲线要素的确定;纵断面设计内容包括纵面线形的绘制,平纵横的协调配合以及填挖平衡的控制;横断面设计内容包括路线横断面的绘制,填挖方量计算;路面结构设计内容包括沥青路面结构层设计,面层厚度的确定等;防护工程设计内容主要是挡土墙形式和尺寸设计。
关键词:高速公路; 平面线形; 纵断面线形; 横断面; 沥青混凝土路面
Construction Design for the 11th contract section of Xi’an to Shangzhou’s Freeway
Abstrac:The terrain of the 11th contract section of Xi’an to Shangzhou’s Freeway is mountainous and hilly areas. Through the calculation of traffic statistics , as well as the amount of engineering ,geological conditions, road construction materials and many other considerations ,finally ,people determine the design speed of 80km / h, roadbed width of , and use the asphalt concrete pavement design. The design includes the three-dimensional design (horizontal design, vertical design, cross-sectional design) , pavement design (asphalt concrete pavement), protection engineering design (retaining walls) and the drainage facilities design. The graphic design includes the determine of the selection of the highway route, the drawing of the horizontal alignment and the curve elements. The vertical design includes the drawing of the vertical alignment , flat vertical and horizontal coordination and balance of control excavation and filling; The cross-sectional design includes the line’s drawing ,and the calculating of excavation and pavement design includes the asphalt pavement design, the setting of surface layer thickness and so on. The protection engineering design is primarily aimed at retaining the form and the size design.
Key words: freeway,horizontal alignment,vertical alignment,cross section,asphalt concrete pavement
