PAGE PAGE 23 珠海市桂山镇中心洲环岛公路设计B标段 摘 要 本设计是珠海市桂山镇中心洲环岛公路设计B标段，主要是环岛三级公路设计。公路全长1866m，设计车速30km/h，双向两车道，不设置中央分隔带，行车道宽3.25m，路肩宽度0.5m，设置1m宽的人行道。 桂山镇中心洲环岛公路是桂山镇区内部交流的重要通道，路网功能定位十分重要。通过查阅相应技术规范，确定公路的等级以及设计需要的各种参数。在平面图中进行选线，确定路线后对路线进行平面线形设计，制作直线曲线转角表。纵断面设计中设计2个竖曲线，竖曲线的设计需满足平纵面线形组合设计中的所有要求。横断面设计由横断面各部尺寸，横断面组成、逐桩横断面图、路基设计表、土石方计算及调配表。路面设计内容中包括路面组成材料及路面结构层。 通过这次设计不但了解建设公路的各个步骤，而且也能熟练的运用鸿业进行辅助设计及运用AUTOCAD进行制图。 关键词：三级公路；平面设计；纵断面设计；横断面设计；路面设计 Bid section B of central island ring road design, Guishan Town, Zhuhai Abstract This design is the design B section of zhongzhou huandao road, guishan town, zhuhai city. The length of the highway is 1866m, the design speed is 30km/h, two lanes in both directions, no central divider is set, the lane width is 3.25m, the shoulder width is 0.5m, and the pavement is 1m wide. Guishan town central zhou island road is an important communication channel within the guishan town, network function positioning is very important. By consulting the corresponding technical specifications, determine the grade of the highway and various parameters required by the design. Select the line in the plan, design the line line after determining the line, and make the corner table of the straight curve. Two vertical curves are designed in vertical section design. The design of vertical curves should meet all the requirements in linear combination design of plane and vertical plane. The cross-sectional design consists of the size of each part of the cross-sectional section, the composition of the cross-sectional section, the pile by pile cross-sectional map, the subgrade design table, the earth and stone calculation and deployment table. Pavement design includes pavement composition material and pavement structure layer. Through this design, we can not only understand each step of highway construction, but also skillfully use Hongye to carry out auxiliary design and AUTOCAD to carry out mapping.
