中文摘要

轉爐石為年產量可觀之煉鋼副產物，若能替代一般鐵路道碴中的天然石碴，將對生態永續產生一大利益。本研究針對轉爐石應用於鐵路道碴之工程效能評估，探討其做為鐵路道碴之可行性。本試驗之轉爐石經過改質法安定化，並參考先進國家與國內鐵路道碴規範，進行一連串的工程性質試驗，再與一般天然石碴比較，評估轉爐石的優劣。試驗證明，轉爐石不僅符合規範標準，單就工程性質來看，亦非常適合做為鐵路道碴使用。惟其為煉鋼副產物，化學性質及對環境之影響仍需多加探討，方使轉爐石應用於鐵路道碴之評估更為完善。
英文摘要

Railway ballast is generally mined from natural stone. If we don't elaborate alternatives, the environment and nature resources will keep being damaged. Basic-oxygen-furnace (BOF) slag is a by-product of steelmaking. If doing more research on BOF slag, it can produce a big benefit to environmental protection and sustainable ecology. The thesis is aimed at the discussion of engineering performance of BOF slag on railway ballast. Experimenting the BOF slag with standards, then discuss the feasibility of using BOF slag on railway ballast. First of all, the BOF slag using in this thesis had being stabilized, excluding the properties of water swelling. Experimenting the BOF slag with advanced countries standards, including Los Angeles abrasion test, impact value test, rail insulation test, lateral resistance test and particle index test. Comparing with normal ballast, which comes from crashed stone, can know the differences. The tests also can find out whether BOF slag can pass the standards or not. Finally, the experiment proofs that BOF slag is better than normal ballast in many test and passes the ballast standards. On the engineering properties of view, BOF slag is very suitable for using as railway ballast. But, BOF slag is byproduct of steel, so it should also pass the chemical and environmental test. Keep researching on this way can make the research more complete and perfect.
