Proposed herein is a shape design of a different rail support block with existing ones for the commercialization of the urban maglev. The rail support for existing test lines adopts monoblock steel sleeper, whereas an individual support system has been proposed to achieve an additional cost savings and to provide an emergency exit. Also, to enhance the easiness of installation and the repairability, alignment adjusting methods suitable for the new design have been devised.

본 연구는 가스사고의 전형적이고 대표적인 폭발사고와 관련하여 LP가스용기밸브 압력정기, 중간밸브(볼밸브) 및 염화비닐호스로부터의 가스누출량이 어느 정도 되는지에 대하여 이론적으로 계산한 가스누출량과 실제 가스누출량에 대하여 실험을 통하여 연구함으로서 체적공간에서의 폭발과정과 점화원 및 사고경위를 조사하는데 중요한 자료로 활용하고 의도적이거나 취급 또 시공상의 부주의에 의한 가스누출 발생시 사고당시 가스누출량을 확인하는데 활용하고자 연구하게 되었다.
