摘要：In view of the multi-field coupling effects such as rainfall infiltration, reservoir water level (RWL) seepage, and fissure seepage, the risk of slope disaster increases sharply. This study takes an open-pit mine in China as the research object. Based on the improved Green-Ampt model as the key objective, the rainfall infiltration model was improved by combining the dynamic changes of the wet front depth in the slope. The proposed model integrates Darcy's law and the mass conservation principle and establishes the coupling mechanism between seepage and stress fields. Numerical verification was performed using comprehensive performance indicators, including the Nash efficiency coefficient, root mean square error, relative standard deviation, mean absolute error, volume error, and relative error. The comparative analysis with the existing models shows that the improved model has higher accuracy and reliability in predicting slope stability under rainfall-induced seepage. The results emphasize the key role of RWL seepage and rainwater pressure in weakening the mechanical properties of the slope through the wetting softening effect. This work provides theoretical support and practical guidance for predicting slope instability caused by rainfall.
