大理至丽江高速公路总体设计理念及方案

The overall design concept and scheme of Dali to Lijiang highway

云南大理丽江高速公路地处高原山区地带,沿线地形地质复杂,不仅是典型的山区高速公路,更是我国第一条通达藏区的高速公路。文章针对大丽高速公路总体设计,分析其建设条件、项目特点,提出总体设计原则,然后分别从路线、路基路面、排水、桥隧、交叉、沿线设施等方面详细论述其总体设计方案,供今后相似工程借鉴。

Dali to Lijiang highway of Yunnan Province is located in mountainous areas of the plateau. There is the complex topography and geology along the highway. And the engineering is very difficult. It is not only the typical mountainous highway,but also the first access to the Tibetan areas of China. According to the overall design of the highway,construction conditions and project characteristics are analyzed,then overall design disciplines are put forward,and the overall design scheme from the aspect of route,roadbed,drainage,bridge and tunnel,cross,facilities is discussed in detail. This overall design concept and scheme provides the reference for similar projects in the future.
