Professor Shenghua Cui's research lab specializes in landslide mechanics and disaster mitigation in seismically active mountainous regions, with a strong focus on the dynamic response, damage accumulation, and failure mechanisms of rock slopes under seismic loading. The lab integrates experimental methods such as shaking table tests with advanced monitoring techniques—including InSAR, optical remote sensing, and acoustic emission analysis—to investigate the deformation evolution and stability of deep-seated landslides. Key research directions include the role of structural discontinuities (e.g., bedding planes, faults, shear zones) in landslide initiation and propagation, as well as the nonlinear damage behavior of rock masses under cyclic loading.

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.
