DIANA
Geotechnical
지반 해석과 지반과 구조물 사이의 상호 거동은 종종 엔지니어들에게 까다로운 문제를 만들어냅니다. 이러한 까다로운 지반 문제들은 DIANA로 빠르고 정확하게 해결될 수 있습니다. DIANA 프로그램은 기초, 제방, 터널, 굴착, 사면 안정, 광산 및 댐 등 다양한 용도로 흙과 암석 물질을 처리하기 위한 광범위한 최첨단 구성 모델을 제공합니다.
간극 수압과 압밀, 지하수 흐름, 지진 및 액상화 문제들에 대한 해석 기능은 가장 진보된 기능 중 하나이며, 간극수압과 응력의 연계 문제를 정확하게 해석하는데 필수적이라 할 수 있습니다. 또한 DIANA는 지반과 상호거동을 하는 강재와 철근 콘크리트 구조에 대한 진보된 기능들을 제공합니다.
