Shenghua Cui 교수의 연구실은 지진 유발 토양 및 암반 산사태의 기계적 거동, 손상 누적 메커니즘, 그리고 복합 구조적 암반에서의 파손 거동을 중심으로 연구를 진행하고 있습니다. 특히 다주기 하중 하에서의 암석 손상 거동과 음향 에미션, 열화상, 디지털 이미지 상관 분석을 활용한 실험적 접근이 두드러지며, 지형의 3차원적 파손 경계와 산사태 유형 간의 관계 규명에도 기여하고 있습니다. 또한, 위성 간섭계 및 현장 모니터링을 융합한 대규모 깊은 기울기 안정성 평가 기법도 개발하고 있습니다.

The 2017 catastrophic Xinmocun landslide was triggered on a bedding slope in the Songpinggou Gully, Maoxian County, China. Previous research primarily focused on the dynamic slope response and deformation characteristics of a single earthquake, and focus on the effect of damage accumulation on slope stability is lacking. The shaking table tests were conducted in this study to understand historical earthquake-induced damage accumulation in bedding slopes. The acceleration amplification coefficien
Abstract The 2008 Wenchuan Ms 8.0 earthquake triggered the Daguangbao (DGB) landslide, of which the shear surface belongs to a thrust bedding fault 400 m below the carbonate slope. After the landslide, a 1.8 km-long inclined sliding face (0.3 km2) was exposed in the south source area. By using shaking table test, the contributions of the fault to the landslide sliding have been studied in this paper. The bedding fault in the test model is simplified as a weak layer with small elasticity and the
Abstract Rock landslides are generally controlled by a series of discontinuous interfaces formed by damage to complex structural rock masses that is related to folds, faults, and shear zones, which provide potential failure boundaries. Based on a detailed case study, the authors illustrate that structural damage not only affects the 3D boundaries of landslides but also significantly controls the initiation mode. In this paper, six large landslides triggered by the 2008 Wenchuan earthquake (Ms 8.
