Abstract

Man-made vibrations from traffic and construction activities are important because they may cause damage to structures. The current literature provides that damages in the urban areas were not caused by direct transmission of vibration, but rather through subsequent settlement caused by soil densification. In this paper. prediction technique of ground borne vibration induced settlement was introduced on the basis of case studies. In situ application technique of the settlement prediction model developed in laboratary was described, and the predicted settlement was compared with the measured settlement from case studies. The settlement from case studies hlatched well with the settlement calculated from the model. The parametric studies of settlement in typical urban site conditions were performed to determine the sensitive parameters and to develop reliable vibration monitoring and interpretation schemes. These demonstrated the potential usefulness of the model for the evaluation and prediction of the vibration induced in-situ settlement of sands.

교통하중이나 건설 작업에 의해 야기되는 지반진동은 인접구조물에 손상을 입힐 수 있으므로 중요하게 관리되어야 한다. 최근 문헌에 의하면 도심지에서 구조물 손상의 주요 원인은 진동파의 직접 전달에 의한 손상보다 지반다짐으로 야기되는 부등침하에 의한 것으로 알려져 있다. 덕 논문에서는 지반진동에 의한 주변침하 예측기 법을 사례 연구를 충심으로 소개하였다. 실험실에서 개발된 침하예측모델의 현장적용기법을 설명하였으며, 사례연구에서 계측된 침하량과 모델에서 예측된 침하량을 비교하였다. 모델에서 예측한 침하량은 실제침하량과 비교적 잘 일치하였다. 전형적인 도심지 상황에서 영향요소 연구를 수행하여 침하예민요소들을 살펴보고 현장에서의 신뢰성있는 진동 계측 및 평가 방법을 제안하였다. 이상의 연구를 통해 사직토 지반에서 진동에 의한 침하평가 및 예측을 위해 개발된 모델의 사용 가능성을 입증하였다.
