| Summary: | 碩士 === 逢甲大學 === 土木工程所 === 96 === Parts of Central Cross-Island Highway were damaged and closed by Earthquake 921. Therefore, Li-Shing path was become main traffic way of Li-Shan district residents, along tribes and farm products. AERE typhoon was stormed on August 1994 and continuity cloudburst on 1995, they caused multiple landsliding and roadbed flowed away. Due to Li-Shing path geology was weakness and shatter, numbers of damaged locations were increased from 70 to 108. Frequent hillside disaster caused traffic obstruction. This research purpose is based on short-middle-term restoration and rebuilding. Improvement of existing conditions repaired damaged locations of Li-Shing path in order to increase safety and maintain basic traffic demands. Effectively realize with geology, hydrology, environment and existing conditions of Li-Shing path. Analyze design principles of short-middle-term restoration and discuss occurrence reasons of numerous damages to be the theorizing base of restoration. Depending on restoration method’s functions and suitabilities evaluate restoration’s results and compare whole effects after previous typhoons, cloudbursts, landsliding attacked. Analyzing and evaluating the restoration methods after particularizing the damage reasons. In accordance with experience of short-middle-term restoration provides long-term restoration methods, suggestions and budget estimation. And expect long-term emergent hillside restorations will be combined short-middle-term restoration methods to achieve performance by exercising effective.
