Hancheng is located in the eastern part of China’s Shaanxi Province, near west bank Yellow River. It at junction active geological structure area. The rock layer relatively fragmented, and landslide disasters are frequent. occurrence often causes a large number casualties along with economic losses local area, seriously restricting development. Although risk assessment deformation mechanism analysis for single landslides have been performed this area lacks traces database. A complete database comprises basic data required study an important requirement subsequent landslide-related research. Therefore, used multi-temporal high-resolution optical images human-computer interaction visual interpretation methods Google Earth platform to construct County. results showed that least 6785 had occurred total was about 95.38 km2, accounting 5.88% average 1406.04 m2, largest 377,841 smallest 202.96 m2. provides basis understanding spatial distribution County, evaluation susceptibility, disaster prevention mitigation work.

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

The stability analysis of rainfall-induced slope failures considers a number factors including the characteristics rainfall, vegetation, geometry slope, unsaturated soil characteristics, infiltration capacity, and saturation degree variations. Amongst all these factors, this study aims to investigate effects antecedent rainfall conditions. A numerical modeling was conducted using finite difference code software on representative with two different types. Two scenarios were followed: first involved application three intensities for varying initial levels between 40% 60%, representing second scenario successive rainfalls typical 50%. impact assessed by determining time required failure during main extreme after preceding durations. Consequently, zone susceptible suggested use as criterion in hazard management, allowing tracking its duration through proposed chart potential failures. Once anticipated critical have been determined meteorological analysis, risk assessment specific can be practical procedure. Accordingly, control mechanism may established detect natural hazard. Furthermore, procedure applied case study, whose insights harmony real conditions failure. Thus, demonstrated significance landslides triggered rainfalls.
