道路设计摘要

This thesis intends to design a Third-class road in hilly area.Hilly area terrain is similar to the plain ,in terms of technical standards,technical indexes of the hilly area and plain area is roughly the same.In the design process,if it is as flat as a pancake, according to the direction of wiring it should be plain as the leading principle;if there are obstacles or should be on site,then add intermediate control points to search;in the steep slope zone, route should along the even slope line.Make the route a best entia in the flat,vertical,horizontal three aspects.Anyhow,highway design to ensure the principles on the economy, traffic safety ,passenger comfort and road beauty to aesthetic , according to the design speed, the expected traffic volume, topography and other natural conditions.In the design process, we should analyse influence of various factors and get the best project after careful comparison analysis.The design content mainly includes: the design of horizontal al
