| Summary: | 碩士 === 國立中央大學 === 營建管理研究所在職專班 === 106 === The mass rapid transit (MRT) is a critical infrastructure and brings convenience and various advantages for a country. In Taiwan, track construction practices of MRT involve many quality management tools/techniques; previous studies, however, seldom focused on and analyzed these tools/techniques for their practical meanings and application in an integral manner. Therefore, this research fills this research gap. In addition, the quality of track construction depends on the construction quality of roadbeds, which relies on workers’ experience. If inexperienced personnel are required to conduct quality management businesses immediately when participating in a track construction site, it is significant for them to understand common defect patterns of roadbed construction and how to use quality management tools to solve the defect; however, existing studies seldom address this aspect. Thus, this research adopts literature review, case studies and expert interviews to analyze common defect patterns of roadbed construction (including ballast and non-ballast roadbeds) and how to properly use management measure to increase construction quality. Construction engineers should be able to easily understand the whole process, standards and management key points of the construction and thus, efficiently achieve high quality track construction.
