PAGE PAGE 30 珠海市平沙新城道路设计B标段 摘 要 本次毕业设计的主题是对珠海市高栏杆经济开发区平沙新城卫东路二期道路进行初步设计。根据本次毕业设计任务书的要求，本次设计的项目是新建项目，设计道路位于珠海市高栏管理区平沙镇，以卫东路二期为对象，总长约1.5公里，道路等级是次干路，设计的车速是40km/h。该项目所在的地方现状标高约为2～4m，土地比较平坦，项目的规划标高为3.8m，项目所处区域多为还没开发的荒地。本次设计的主要内容包括路线设计、纵断面设计、横断面设计、平面交叉设计和路面结构设计五个部分。首先根据任务书提供的条件查找相关规范和文献确定设计需要的各种参数，选择路线和设置曲线，然后确定纵断面和横断面各种要素并绘出纵断面图和横断面图，接着设计平面交叉口，最后进行边坡设计并确定路面的各个结构层组成及材料。 关键词：路线平面设计；纵断面设计；横断面设计；平面交叉设计；路面结构设计 Section B of Road Design for Pingsha New Town, Zhuhai Abstract The theme of this graduation project is the preliminary design of the second phase of Weidong Road, Pingsha New Town, Zhuhai High railing Economic Development Zone.?A- ccroding to the requirements of this graduation design task book, the design project is a new project. The design road is located in Pingsha Town, Gaolan Management District, Zhuhai City. The total length of the second phase of Weidong Road is about 1.5km. The road grade is sub-trunk road and the designed speed is 40km/h.?The current elevation of the place where the project is located is about 2-4m, the land is relatively flat, the planned elevation of the project is 3.8m, and the area where the project is located is mostly undeveloped wasteland. The main content of this design includes five parts: route design, profile design, cross section design, plane crossing design and pavement structure design. First, according to the condi- tions provided by the task book, find the relevant specifications and documents to determine the various parameters needed for the design, select the route and set the curve, then deter- mine the various elements of the profile and cross section and draw the profile and section view, and then design the intersection.?Finally, the slope is designed and the composition and materials of each structural layer of the pavement are determined.
