库区公路绿道建设的设计要点浅析

Analysis on Design Points of Highway Greenway Construction in Reservoir Area

公路绿道建设的日益兴起,因其在不同地形地貌条件下需结合不同的设计理念、设计方法来设计具有特色的公路绿道。本文结合浙江省淳安县绿道的建设经验,对千岛湖库区已有公路增设绿道的建设特点进行阐述,从地质、断面布置、平纵设计、路基路面、桥梁涵洞、交安及沿线设施、景观绿化等工程设计的角度进行总结分析,着重对断面布置和平纵设计进行研究,提出库区公路绿道的合理的设计指标或设计方法。

The construction of highway greenways is rising day by day, because it needs to combine different design concepts and methods to design characteristic highway greenways under different terrain and geomorphic conditions. Based on the construction experience of greenways in Chun’an County, Zhejiang Province, this paper expounds the construction characteristics of adding greenways to existing roads in the Qiandao Lake Reservoir area, summarizes and analyzes the angles of engineering design from the aspects of geology, section layout, horizontal and vertical design, subgrade and pavement, bridge and culvert, traffic safety and facilities along the line, landscape greening, etc., focuses on the study of section layout and vertical design, and puts forward reasonable design indicators or design methods for highway greenways in the reservoir area.
