Abstract
The regional landforms of Anshun to Ziyun Expressway are mainly in the karst and erosion low mountain landscape, especially Yangwu Town to the end section where heavier terrain fluctuation, complex and varied topography, large scope of fault fracture zone, karst cave, water outlet, karst warehouse, underground river, and consequent slope are dominated. Fixing road alignment in the complex geological areas requires first to investigate the route topography and geological conditions, then to study main engineering geology characteristics on each section and collect key factors related to route layout in order that the reasonable and feasible alignment plan and comparison suggestion can be finally proposed. This article addresses the application of comprehensive geological route selection technology during the project final survey period to allow the recommended alignment plan to appropriately pass fault fracture zone, karst cave, water outlet, underground river and the consequent slope. Therefore, the recommended alignment of this project is proved safe, economical and reasonable.关键词
