【摘要】：当前高速公路建设的重点逐渐向地形复杂的山区不断延伸,由于我国地域辽阔,地形、地貌差别极大,而山区建设条件又及其复杂,生态环境脆弱,极易出现水土流失、生态破坏、环境污染等一系列的环境问题。本文以山西阳城至蟒河高速公路新建工程为研究对象,对山区高速公路选线方法进行系统理论研究。首先对影响山区高速公路选线的地形地貌、地质构造、地物和矿产资源分布等建设条件和沿线主要环境敏感点进行了特性分析。其次针对山西阳蟒高速公路的特点,从最大限度地利用路线走廊带内的空间资源,尽量减少对高速公路走廊带内的生态环境影响,集约利用通道资源,合理避让自然保护区、水源保护地,充分保护自然区的完整性和原始性,实现公路与自然的协调发展等方面,对走廊带内可能的路线方案进行了系统性的比选、优化,提出了适合本项目的推荐方案和具有价值的比较方案。最后,针对山西阳城至蟒河高速公路路线方案影响因素繁多而且非常复杂的特点,通过建立AHP-TOPSIS评价模型,对各比选方案进行了多指标定量分析,从而提高了山区高速公路选线的科学性,促进了公路建设与自然环境的和谐统一。本文以山西阳城至蟒河高速公路为依托,示范性地将绿色公路理念应用到了山区高速公路建设中,路线选线过程中以不破坏当地生态为前提,合理选定路线平纵面线形,尽可能减少对沿线环境敏感点的干扰,同时力争减小工程规模,降低工程造价,实现高速公路建设与自然生态的和谐发展。
[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.
