Abstract

Rainfall is a significant factor of bank slope collapses. In this study, the effects of rainfall intensity and type on bank slope stability are investigated. By establishing non-ponding infiltration models and ponding infiltration models, the bank slope stability model considering rainfall is proposed. The results show that rainfall infiltration rapidly increases the water content of the bank soil, the safety factor of bank slopes decreases rapidly, and may even lead to the instability of bank slopes. In addition, the type of rainfall also has an important effect on slope stability, where the early occurrence of rainfall peaks affecting the slope safety factor earlier, and the later occurrence of rainfall peaks threatening the slope stability more seriously. The study highlights the importance of precautionary measures to cope with extreme rainfall in the design and management of bank slopes, including monitoring and predicting changes in bank slopes and implementing effective protective measures and drainage systems to maintain bank slope stability.
