Abstract

In accordance with the urban development project, cases of constructing temporary wall structures for ground excavation in the vicinity of railway structures are increasing. In addition, the complaints about train vibration are also increasing from people living in large buildings newly built after installing the temporary wall structures. In order to solve this problem, a method for reducing train vibration is considered from the design stage of the building, and a vibration reduction system is installed on the structure when the building is newly constructed. However, the vibration reduction method established at the structure design stage can be determined through the results of field measurements or dynamic numerical analysis for a specific area, and there is a limit to evaluating whether the established vibration reduction method is appropriate due to the lack of objective research data. Therefore, in order to provide objective basic data when establishing a vibration reduction method, this study performed the dynamic numerical analysis for a operating train with a speed 80km/h by applying differently the depths of railway structures, the distances between railways and temporary wall structures, and ground conditions. It was found that the range of influence of a train operating at 80 km/h was within 4.5D of the lateral distance from the railway structure in the case of the condition where the temporary wall was installed.

도심지 개발사업에 따라 철도구조물 인근에서 지반굴착을 위한 가시설 구조물을 시공하는 사례가 증가하고 있다. 또한 가시설 구조물 설치 후 신축한 대형건물에 주거하는 사람들로부터 열차진동에 대한 민원도 증가하고 있다. 이와 같은 문제를 해결하기 위해 건물의 설계단계부터 열차진동을 저감하기 위한 방법이 고려되고, 건물 신축 시 구조물에 방진시스템이 설치된다. 그러나 구조물 설계단계에서 수립되는 방진대책은 특정 지역에 대한 현장계측 또는 동적 수치해석의 결과를 통해 결정할 수 있고, 객관적인 관련 연구 자료가 부족하여 수립한 방진대책의 적정성을 평가하는데 한계가 있다. 이에 본 연구에서는 방진대책의 수립을 위한 객관적인 기초자료 제공을 목적으로 수치해석을 통해 철도구조물의 심도, 철도와 가시설 구조물의 이격거리 및 지반조건을 달리하여 시속 80km/h인 운행열차를 대상으로 동적 수치해석을 수행하였다. 연구결과, 시속 80km/h인 운행열차의 영향범위는 가시설 벽체가 설치된 조건의 경우 철도구조물로부터 이격거리 4.5D이내인 것으로 나타났다.
