摘 要

本毕业设计的主要内容为义乌市宗泽路延伸工程施工图设计。宗泽路延伸道路呈西北—东南走向，为城市主干道。道路起点与现状下穿江东路地道相接，起于东洲路口，终点与新外环路互通立交设计分界线相接，全长2890m。道路设计车速60km/h，红线宽55m，按双向八车道设计。

本次设计根据道路勘测设计基本原则以及路基路面工程基本理论，综合考虑当地的技术和经济条件，严格按照施工图设计过程进行独立作业，主要包括路线设计、路面结构设计以及道路绿化设计，各项技术指标均要满足相关规范的要求。需要注意的是本设计为城市道路设计，应充分考虑城市道路的选线原则，针对义乌市城市总体规划和城市主干路延伸工程的设计要求进行相关设计工作。

Yiwu City Zongze Road Extension construction drawing design

ABSTRACT

The main content of the graduation design for the Yiwu City, Zongze Road extension works construction design. Zongze Road extension road was northwest - southeast to the city main road. Road starting point and the status quo along the Jiedong Road tunnel phase, from the junction of the East Island, the end of the new interchange with the new interchange design line, phase length 2890m. Road design speed 60km / h, red line width 55m, according to two-way eight-lane design.

This design is based on the basic principles of road survey and design and the basic theory of roadbed pavement engineering, taking into account the local technical and economic conditions, in strict accordance with the construction design process for independent operations, including route design, road structure design and road green design, Technical indicators must meet the requirements of the relevant norms. It should be noted that the design for the urban road design, should take full account of the principle of urban road selection, Yiwu City for the overall planning and urban trunk extension project design requirements related to the design work.

Key words：Urban road;Road structure design; Longitudinal design; Cross-sectional design;
