Studying the lateral displacement of retaining wall supporting sandy soil under dynamic loads
Open EngineeringWhen Rankine or Coulomb theories are used to design a retaining wall, it is accepted that the retaining wall will experience a lateral displacement. By allowing the wall to move laterally, the earth pressure decreases on the active side of the wall and ...

Experimental Analysis of Vibration Transfer Characteristics of an Elevated Railroad Station
Journal of The Korean Society of Disaster Information, 2015 선하역사 내부에 발생하는 소음을 저감하기 위해서는 진동의 감소가 필요하며, 보다 효 과적인 진동 저감 대책 수립을 위해서는 궤도-접속교량-구조물의 상호작용 특성을 감안 하여 열차 운행으로 발생하는 진동이 전달되는 경로 및 특성에 대한 명확한 이해가 필 요하다. 이 논문에서는 국내 선하역사 현황을 구조적으로 분류하고 대표 선하역사에 대 한 진동 측정을 통하여 역사에 발생하는 진동의 전달 특성을 분석하였다. 주파수응답을 통한 분석 결과 궤도의 진동이 역사로 전달되면서 고주파 성분이 큰 감소를 나타냈으 며, 일부 역사에서 저주파 대역 내 증폭 구간이 발견되었다. 플로팅궤도가 적용되거나 TPS 구조의 역사는 궤도로부터 전달되는 진동이
