It is obvious that traditional engineering methods can not satisfy the needs for modern highway bank reconstruction. Ecology engineering (EE) has been widely suggested and valued because of its concepts. Not only does it cohere with roadwork requirements, it also preserves ecological balance and natural resources. However, there are numerous reconstructional methods, and no rational means of selecting those that take into consideration natural and artificial factors systematically have been established. Thus, this research develops a quantified judging model that improves the capability to choose the best reconstructional methods. This research discusses and analyzes the practical application of highway bank reconstruction methods in terms of EE concepts. Firstly, recent successful and failing cases which EE methods were employed were collected and examined. In order to investigate their adequacy, DAHP was then used to select and arrange the most proper reconstruction method. Furthermore, Sensitivity Analysis was utilized tochoose the most applicable method. Finally, the adequacy of the method was confirmed by practical reconstructions. Results showed that highway bank reconstructional method choices depend heavily on the environment and should be selected accordingly; the restrictions in collapsing environments should also be examined carefully. In conclusion, different reconstructional methods should be employed togetherto achieve the greatest effect from both ecological engineering and traditional reconstructional methods.
