Research on Environmental Protection Route Selection of Xi'an Shiyan High-speed Railway
The section from Xi'an to Shangluo of the Xi'an to Shiyan high-speed railway crosses the Qinling mountainous area and the section from Yunxi to Shiyan crosses the Han River.It has the characteristics of large topography,complex geological conditions,dense environmentally sensitive areas,rich biodiversity,and strict water environmental protection requirements.The Protection of the ecological environment of the Qinling and Han River basins became an important factor which restricted the route plan in the construction of the high-speed railway.By adopting the technology of GIS+BIM,a layer of regional environmental sensitive areas was created,and a multi-dimensional environmental protection target spatial distribution and control range environmental protection route selection platform was built.Based on the engineering technical conditions,a comprehensive comparison of the environmental feasibility and environmental impact degree of each plan was carried out,and the route plan with the smallest environmental impact was recommended,providing strong support for the design,route selection.The results show that,by carrying out special demonstration of environmental impact of road sections in sensitive areas in advance,it can further optimize the selection of engineering routes and engineering forms,and ensure the compliance of the project according to law.
