英文摘要: Abstract(#br)As sudden catastrophic geological disasters, landslides always cause numerous casualties and much property damage. Landslides in reservoir areas are rarely caused by a single influential factor such as rainfall or fluctuation of reservoir water level (FRWL); rather, they are frequently caused by the combination of influential factors. Since rainfall and FRWL conditions vary by location in reservoir areas, it is necessary to discuss slope stability under various possible combinations of rainfall and FRWL while considering the specific characteristics of the region. In this paper, model tests on the slope stability of the Three Gorges Reservoir (TGR) area were conducted with S1 sand under three different rainfall and FRWL combinations. Additionally, numerical simulations on the...
