부정형한 기반을 갖는 표층지반의 공진 시 지반 진동 증폭

초록

Earthquake observations at different sites within alluvial soil deposits have demonstrated that buried underground structures follow closely the motion of the surrounding soil. Therefore, it is usual in a seismic design process to apply free-field ground displacements through Winkler-type soil springs to a underground structure in order to evaluate stress patterns induced within its structural members. This paper provides clear understandings of resonant ground vibration modes and strain rates of surface soil deposits with irregular geometry of a basin.
