Abstract

Seepage induced earthern slope failures occurs in concert with meteorological events when large quantities of groundwater are channeled into slopes through infiltration. The presence of flowing groundwater in earthern slopes can induce ground failures that result in significant property damage and potential loss of life. Seepage induced earthen slope failures represent a serious problem in geotechnical engineering. This research applies existing fluid-solid numerical modeling capabilities to the study and prediction of seepage induced earthen slope failures. Study of the targeted application holds potential for much needed advances in geotechnical engineering analysis technology which could be used to design more effective engineering slope stabilization interventions.

침투에 의한 토사사면의 붕괴는 기상학적인 현상과 더불어 많은 양의 지하수의 유입에 의하여 발생한다. 토사사면 속에 존재하는 지하수의 흐름은 심각한 재산 및 인명손실의 잠재적인 요인으로 작용한다. 이러한 침투에 의한 토사사면의 안정성 문제는 지반공학에서 중요한 문제로 인식되어져 오고 있다. 본 연구는 기존의 유체 및 고체의 상호 작용에 대한 수치모델링 기법을 이용하여 침투에 의한 토사사면붕괴의 이해 및 이를 예측하기 위하여 수행되었다. 본 연구는 지반공학에서 중요히 다루는 사면안정화기법 연구에 효과적인 기술적 기여에 중점이 있다.
