철도인접지역 건물에 대한 진동전달율의 영향성 평가

For train vibration influence assessment of newly constructed buildings in building design levels, 4 train measured vibration acceleration responses were used to compare with TR theory values and suitability of TR values was proposed. Through this TR method, construction planned grounds located near railroad areas were selected and ground vibration measurement was conducted. Through natural frequency by MIDAS, vertical acceleration response, and ground frequency from measured vibration response, TR was calculated and vibration prediction was conducted. As a result of comparing acceleration response estimate applying TR and measured value of train vibration acceleration response, it was found that it was in 3.61% ∼ 37.1% of margin of error. Clear peak of 7.19~10.61Hz in KTX, Gyungeuisun, and cement train were confirmed.
