| Abstract: | Considering the engineering performance of the red-bed soft rock,based on a wide investigation and a technical and economic study of existing freeway project in several provinces in western China red-bed soft rock area,a comprehensive evaluation indicator system was established for cutting and tunnel alternative assessment with gray relational analysis method.The objective of the research is mainly to get the critical height between cutting and tunnel in order to determine which alternative could be used rationally between cutting and tunnel.The result provides helpful reference for decision-making in freeway design and construction in red-bed soft rock area along a cutting segment. |
