| Summary: | 碩士 === 國立雲林科技大學 === 營建工程系 === 104 === The ongoing Taichung MRT green line project use a lot of prestressed concrete sleepers. Before mass production of PC sleepers, an design approval test is required to verify the performance of the sleeper. The sleeper design of Taichung MRT system is quite similar to that of Taipei MRT system, both refer to code chapter 03426, sections 3.9 and 3.10 for the design approval test. The Yuntech material testing and supporting center conducted the design approval test in 2015 spring. The test items includes sleeper bending test, fastening insert test, fastening uplift test, fastening repeated load test, fastening longitudinal restraint test, fastening transverse restraint test. We improved the test setups and procedures according to the specified test methods and completed the design approval test within 5 weeks. The laboratory testing experience can be borrowed in the future projects.
