“…PLAXIS can handle various geotechnical issues, including tunnels, deep excavations, earth structures, retaining walls, and slopes [183]. Notably, the database reveals a significant number of researchers [184][185][186][187][188] implementing the FDM using FLAC2D/3D computer program. Likewise, Geostudio software based on the FEM has also been significantly used in these studies [57,107,113,189].…”

An extensive evaluation of published articles suggests a lack of research on a systematic literature review relating to physical modelling techniques, developments and application in slope stability studies. However, there is growing interest in using physical model tests in slope stability investigations. The present study systematically reviews the methodologies and applications of physical modelling in slope stability research. The Scopus database was used to identify relevant studies which employed physical model tests in slope stability investigations. A combination of fifteen keywords was used to identify relevant articles. A PRISMA-P method for conducting a systematic review was adopted. Articles were screened and analysed, and extracted data were re-organised using an Excel sheet. Data relating to research objectives, physical model test techniques, instrumentation, scaling laws, numerical modelling, results, and findings were extracted and analysed. The systematic review highlights gaps requiring further studies, particularly in slope reinforcements using vegetation and strength deterioration of reinforcements performance under repeated loading exposures. It is found that scholars have not fully addressed the influence of loss of water on pore water regimes and its impact on stability when vegetation is applied as reinforcements. It is also found that the development of slope materials for soil slopes in physical model tests relies on the artificial development of such materials with minimal consideration of their long-term behaviour. Although other options, such as bio-cementation and desiccation techniques, which simulate the natural environment of the slopes, are neglected in slope material development, the present study recommends that future studies consider such techniques.

“…When seismic waves are transmitted to the site, the rock masses in the area were broken up due to earthquake shaking, leaving the loose structure and lower integrity of the rock masses (Massey et al 2016). In addition, since the acceleration on a slope surface increases with the slope gradient (Wang et al 2019b), the seismic tensile stress on the slope surface causes more severe damage to rock masses. The steeper the slopes, the more signi cant increment in acceleration (Yasuda et al 2016;Wang et al 2019b).…”

Identi cation of the locking segments is crucial for assessing the potential runout risk and the overall stability of the high-locality landslide. However, during the eld investigation, it is di cult to identify the locking segments before landslide failure due to their concealment. Tizicao landslide, a high-locality landslide, is used as the eld example for the locking segments identi cation analysis in this study.Based on the geomorphology and spatial-temporal deformation in the landslide, the identi cation characteristics of the locking segments of the landslide are analyzed macroscopically, and the location and area of the locking segments are determined based on the analysis results. The eld investigation methods are used to verify the identi cation results, including the monitoring of surface and deep displacement, geological borehole drilling, and oblique photography using drones. The results show that the locking segment of the Tizicao landslide lies at the southern slope toe, which covers an area of about 4.69 × 10 4 m 2 , accounting for 15.2% of the total area of the landslide. The signi cant different developmental characteristics are observed in respect of the surface displacement, deep displacement, surface crack, and sliding zone soil between locking and non-locking segments. It is concluded that the formation and evolution of the locking rock masses in the Tizicao landslide are closely related to the development of local folds and S-shaped river valleys, differential unloading due to river cutting, and earthquake-induced damage to rock masses in the landslide area.
