Reliability evaluation of reservoir bank slopes with weak interlayers considering spatial variability

Frontiers in Marine Science, 2023
Reservoir bank slopes with weak interlayers are common in the Three Gorges Reservoir area. Their stabilities are affected by multi-coupled factors (e.g., reservoir water fluctuations, rainfall, and earthquakes in the reservoir area).
