| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 94 === It has become more and more common to open up roads in mountains, conversely,
landslides accompanying such actions occur more often as well. 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.
