Urban subways usually make environmental problems because subway vibrations are transmitted to building structures. However, when the buildings are designed, vibrations due to subway are not usually considered in advance. This results in many environmental vibration problems after buildings are constructed. This study was carried out to set up and evaluate a pre-assessment technique for the environmental impact of urban subway vibration on newly planned buildings near a subway line. for this purpose, semi-emperical method was set up and vibration measurements were made on site in accordance with construction schedule. Computer simulation was also performed using ANSYS software to predict the building vibration and compared with the measured results for evaluation of the pre-assessment technique.

급속한 도시화와 인구 고밀도화에 따라 수반되는 교통문제와 생활공간의 확보는 대부분의 대도시가 직면한 사회적 문제이다. 특히 교통문제 해결을 위해 서울시가 추진하고 있는 지하철 건설은 밀집화 된 도시의 공간활용 측면에 있어서 필연적이라고 할 수 있다. 서울시 지하철은 40% 이상의 높은 수송 분담율을 기록하고 있다. 그러나 양적인 증가에 반해, 공간적인 밀폐성 증가로 인한 대기질, 소음·진동 환경 의한 시민들의 건강 위해성 악화가 논란의 대상이 되고 있다. (중략)

효율적인 진동환경관리를 위해 GIS Software를 사용하여 개발된 진동환경관리시스템(Vibration Management System : VMS)을 점진동원과 선진동원에서의 진동관리에 적용하였다. 점진동원에 의한 진동관리를 위해서는 발파진동을 예로 들었으며, 선진동원의 경우는 지하철 운행시의 교통진동에 의한 인근지역에서의 진동환경을 분석하였다.

In this paper the characteristics of vibration induced by subway trains running on track is discussed. The quantitative prediction of the vibration level and the countermeasure for reduction of necessary, is of importance for the better environment. It was made the constructed Bundang line as first step with the modified Young-Dan type to basis on the Japanese Young-Dan type. In this paper it was measured and analyzed to two region ($ \circled1$Susuh-Bokjung. $ \circled2$Chorim-Suhyun region) of this. at present, operational Bundang line when averaging velocity of train is 60 (km/h). As the response characteristics of frequency Induced by subway operation, it was confirmed that frequency band of neighborhood of 30~80 Hz in generally dominant. Also to assess the quantitative nitration as response level to be measured for each point of two region in subway operation, the vibrational response level was measured at the state to be not subway operation. And the level was approximately $\fraction one-fifth~\fraction one-ten$ level comparing to subway operation.

Subway train-induced ground-borne vibration is studied. Previously used vibration level prediction equations are reviewed. Measured vibration levels are compared with the predicted results and numerically computed results. The results show that vibration level does not decrease proportionally with the distance.

Predictions of vibration induced by subway operation has been studied through comparison between the measurement values and the estimated values which proposed by other scientists to determine the adequacy of each equation. It was found from this study that the Wilson's prediction equation gives the best overall approximation value although the peak frequency band lies somewhat higher than that obtained from measurement.

Noise and vibration induced by subway operation is one of the major problem for the residents living nearby railway tracks. Many scientists and engineers have been working on proposing the more accurate prediction equation of noise and vibration to provide the better residential environment. Some predictiction equations were determined to compare the measurement value of a noise obtained from the inside of a residential area. It was observed that the condition of a soil type is one of the major parameter which should be considered to obtain the more accurate prediction value of a noise.
