<p>As a prevalent form of geological hazard, landslides have been a key focus of numerical simulation research aimed at elucidating failure mechanisms, assessing slope stability, and supporting disaster prevention and mitigation. This study applies bibliometric analysis to systematically evaluate the evolution of landslide numerical simulation research from 1995 to 2024, using data from the Web of Science Core Collection. A total of 906 publications were identified, representing contributions from 56 countries, 921 institutions, and 3190 authors. The development of the field is characterized by three distinct phases: the embryonic stage, the exploratory stage, and the developmental stage. Research hotspots primarily center on triggering mechanisms, stability analysis, landslide dynamics, and simulation methodologies. The findings highlight China and Italy as leading contributors in both publication volume and academic impact. Core journals such as Landslides and Engineering Geology have served as principal platforms for disseminating key advances. This study provides a comprehensive theoretical and data-driven foundation to support future research and development in landslide numerical simulation.</p>
