Inspired by two practical cases in Switzerland, the paper investigates a problem of elevated earth pressures downslope of existing landslides. This problem is relevant for both permanent landslides andone-time events, and of particular practical interest is the area of the stable slope just below the landslide high-pressure compression zone. Intuitively, there should be a transition zone, within which high landslide pressures subside to the far field (at rest) earth pressures in the stable slope. How large is this transition zone and how fast do the earth pressures decrease away from the slide? The paper proposes a basic mechanism of the downhill pressure transfer within the stable part of the slope below a landslide.The mechanism combines the failure at the bottom of the unstable part of the slope with progressive growth of the slip surface into the stable part, accounting for the groundwater flow and potential presence of embedded structures. It allows the determination of the dimensions of the ‘landslide influence zone’ below the landslide and the lateral earth pressures within it, providing some insights fordesign considerations and future hazard mapping.
