山西陽(yáng)蟒高速公路選線技術(shù)研究
[Abstract]:At present, the focus of highway construction is gradually extending to the mountainous areas with complicated terrain. Because of the vast territory, the great difference of terrain and geomorphology, and the complex conditions of mountain construction, the ecological environment is fragile, and soil erosion is easy to occur. Ecological damage, environmental pollution and a series of environmental problems. Based on the new construction project of Shanxi Yangcheng-Benghe Expressway, this paper makes a systematic and theoretical study on the route selection method of mountain expressway. Firstly, the characteristics of the construction conditions, such as topography, geological structure, distribution of ground objects and mineral resources, and the main environmental sensitive points along the highway in mountainous areas are analyzed. Secondly, according to the characteristics of Shanxi Yangcong Expressway, we should make maximum use of the space resources in the corridor zone of the route, minimize the ecological environment impact on the corridor belt of the highway, make intensive use of the channel resources, and avoid the natural reserve reasonably. Water conservation sites, to fully protect the integrity and originality of natural areas, to achieve coordinated development of highways and nature, etc. have been systematically compared and optimized for possible route schemes in corridor zones. The recommended scheme and the valuable comparison scheme for this project are put forward. Finally, in view of the various and very complex factors affecting the route scheme of Yangcheng to python River highway in Shanxi Province, through establishing the AHP-TOPSIS evaluation model, the multi-index quantitative analysis of each comparison scheme is carried out. Therefore, it improves the scientific nature of highway route selection and promotes the harmony and unity of highway construction and natural environment. Based on Shanxi Yangcheng to Python River Expressway, this paper applies the idea of green highway to the construction of mountain highway. The route selection process is based on the premise of not destroying the local ecology and reasonably selecting the horizontal and vertical line shape of the route. As far as possible to reduce the interference to the sensitive points along the environment, at the same time strive to reduce the scale of the project, reduce the cost of the project, and achieve the harmonious development of highway construction and natural ecology.
