Abstract
최근 철도시설 하부와 주변에서 이루어지는 지하터널 굴착작업은 대부분이 발파작업으로 이루어지기 때문에 발파진동으로 인하여 철도시설물에 손상을 줄 뿐만 아니라 열차운행 안전에 심각한 문제가 발생할 수 있다. 일반적으로 철도시설물에 대한 발파진동 허용기준은 0.3cm/sec으로 설정하여 설계와 시공이 이루어지고 있는데, 발파진동 허용기준이 철도시설물의 구조적, 재료적 특성으로 볼 때 너무 낮게 설정되어 있다. 본 연구는 경부선 철도에 운행되고 있는 다양한 열차의 진동을 수회에 걸쳐 측정하여 열차진동의 특성을 분석하여 발파진동 특성과 비교분석하고, 열차진동 측정값, 국내 도로 및 산업시설물 관리기준, 철도안전관리 시행세칙의 지진 황색경보 조치기준 등을 종합적으로 분석하여 철도시설물에 대한 발파진동 허용기준을 제안하였다.
Recently, underground tunnel excavation work under and around railroad facilities is mostly performed by blasting, so blasting vibration not only damages railroad facilities but can also cause serious problems in train operation safety. In general, blasting vibration limit for railway facilities is set to 0.3 cm/sec, and design and construction are performed; however, the blasting vibration limit is set too low in view of the structural and material characteristics of railway facilities. This study proposed a blasting vibration limit for railway facilities by measuring and analyzing the vibration of various trains operating on the Gyeongbu Line several times and comparing observed values with blasting vibration characteristics, domestic road and industrial facility management standards, and earthquake alert level standards for railway safety management.
