Mountain Highway Environmental, Geological And Operational Security Line Selection And Evaluation Studies

Highway construction is a very complicated engineering activities, and it affectedall aspects of society, economy and environment. Mountain road is an important part ofthe transport of our country, the fragile mountain ecosystems will be a severe challenge，environmental problems involved in the construction of highway in mountain area ismore and more serious and prominent, such as soil erosion, ecological pollution, waterpollution, noise pollution and so on.Line selection is the key to ensure highwayconstruction and environmental protection coordinated development, thus advocatingenvironmental protection has been crunch time line selection, on the mountainenvironmental route selection for specific research, to explore the methods andCountermeasures to realize the coordinated development of environment and humanengineering activities, not only has theoretical value, but also has the profound practice.In this paper, the mountainous highway environmental route selection arediscussed in detail, the conclusion are as follows:Discussed the basic principle, the mountain environmental route selection shouldtake the basic steps, the basiccountermeasures, at the same time, a detailed analysis ofthe separated subgrade and integral subgrade, the high embankment and viaduct anddeep cutting and tunnel of the strengths and weaknesses of the demostration, mountainring and line selection gives direction and ideas more clear.Through the analysis of Chongqing Wuxi to Shaanxi highway engineering,landform, climate and hydrology, environmental sensitive area index, on route fourplans were compared, and ultimately determine the consideration of environmentalfactors in the mountain road line selection scheme. The mountainous area highwayconstruction environment focused on avoiding and Coordinating Integration on theenvironmental sensitive area, saves the precious land resources.
