Summary: | 碩士 === 國立宜蘭大學 === 建築與永續規劃研究所碩士班 === 101 === Taiwan is a densely populated country, with mountains and hills accounting for more than 70% of the land. However, under the trends of enhancing the economy and balancing urban and rural development, the freeway network has expanded towards the mountain areas. Freeway maintenance authorities will face a different challenge in response to both geographical and environmental change.
On the 25th of April, 2010, four people were killed in the landslides in National Freeway No. 3 3.1K. It also impacted the rights of hundreds of thousands of road users. In view of the environment change and maintenance system omission, freeway maintenance authorities have planned to improve the existing maintenance system, and organise the safety assessment and inspections for freeway slope reinforcement work, to effectively prevent slope collapse happening again.
This study focuses on the measures taken by the relevant authorities after the National Freeway No.3 3.1K event. The measures have two main dimensions: One is to fully detect the slope area, perform a slope safety assessment, reinforce design, and improve project execution. The other one is to take preventative measures by improving both maintenance inspections and monitoring mechanisms.
This study firstly conducted the literature review to understand the meaning of maintenance management for the public sector, and also the fundamental issues of the maintenance system and the causes for collapse. It further collected the information of the regulations and principles announced in the past two years. Finally, the study compared the existing regulations to the actual outcome, and explored the reasons for the differences as well as the implementation performance. It is hoped the study will promote the freeway maintenance policy and procedures from the authorities.
