长江沿岸某山区高速公路路线方案研究

Study on Route Scheme of a Mountainous Expressway along Changjiang River

摘要:

针对长江沿岸某山区高速公路路线走向选择问题，从地质、安全和环境三个方面阐述了山区高速公路路线选线需要注意的要素，并提出了多个路线方案。在多方案比选的基础上，从路线与巴张高速的衔接，工程规模、投资、施工难度，地方政府意见等方面对影响路线方案的控制因素进行了定性分析，提出了确定路线方案的原则，并对各个控制因素进行赋值。通过计算各方案的控制因素分数总和，确定A线方案为推荐方案。

Abstract:

Aiming at route alignment of mountainous area highway bank of the yangtse river, we presented several scheme to compare. On the basis of analyzing influencing corridor solution selection factors, the paper analysed the weight of every factors and chose assignment. A route scheme selected as the recommended corridor for the project after qualitative analysis and quantitative analysis. As a typical mountainous highway, it is expected that the paper will have a certain reference value for the selection of the mountainous area similar to the corridor of the highway in preliminary program research.
