摘 要

本设计是根据所提供的资料,该路段的地形、地貌、地质、沿线构造物、水文等自然条件,对原始数据进行分析，再依据《公路工程技术标准》 、《公路路线设计规范》等交通部颁发的相关技术指标,在老师的指导和同学的帮助下完成的。

设计详细资料有：路线设计，路线平、纵、横设计；路基防护及排水设计，沥青路面设计，挡土墙设计。

计算域调配；在老师指导和要求下完成应用计算机绘制工程图。 整个设计计算了路线的平、纵、横要素以及工程概算,设计了路基、路面、及沿线附属设施等内容,由此圆满完成了杭集A5线 K0 0.000—K2 167.932 段二级公路的初步设计。

关键词：路线，路基，路面，排水，土方石计算与调配。

ABSTRACT

The design is based on the section of the topography geology sbsidiary facilities along hydrology and other natural conditions to analyze the raw data and then based on “highway engineering standards”,”highway route design” and other transport relevant technical specifications issued by the Ministry, with the help of teachers’ and students’ guidance.

Details of the design include :Route design the paper up settles the lines(mountain range area or more mountain range line),Draw the route plane chart. Proceed route vertical section of design; Roadbed design. Complete two kilometer cross section are with the roadbed the calculation of square ground and roadbed drain the design; Road design. concrete road design and Asphalt road design. Complete a route flat surface to cross; Complete retaining wall design; Design budgetary estimate establishment: Completes the entire line to design the road section the preliminary design budgetary estimate; The application calculator draws the engineering diagram, Complete under the teacher’s leading request. I compute the route even vertical, horizontal main factor. Also, I designded the flat surface of the roadbed and the road size for ubsidiary facilities along, fromhere. Though the part ahead, I completed Hangji Province highway of B7 line in section two stages preliminary designs.

Keywords: Route, Roadbed, Road. Budgetary estimate
