Since the construction and operation of the Three Gorges Water Conservancy Project (TGWCP), a series of geological safety issues have inevitably emerged within the reservoir area, severely affecting the safety of navigation, towns, roads, and residents within the Three Gorges Reservoir Area (TGRA). This study focuses on the geological safety issues that have arisen during the construction and operation of the TGWCP. The methods involved in the entire research process include data collection, field investigation, and literature review. The following conclusions are drawn: the geological safety issues experienced in the TGRA can be divided into three stages: the natural primitive stage (before 1993), the construction stage (1993–2009), and the operational stage (since 2009). The construction stage can be further divided into three phases, corresponding to the timelines of the resettlement projects: phase 1 (1993–1997), phase 2 (1997–2003), and phase 3 (2003–2009) of the resettlement project. In the natural primitive stage, geological safety issue is primarily triggered by natural factors, leading to landslides and collapses. During the construction stage, the geological safety issues in phase 1 of the resettlement project are induced by human engineering activities, resulting in landslides, collapses, and debris flows. In phase 2 of the resettlement project, the geological safety issues are related to the resurgence of ancient landslides caused by the reservoir water level to 1...
