Abstract

The traditional approaches to landslide drainage never provide adequate drainage capacity over the long term. Therefore, a new drainage system free of these drawbacks must be developed. Based on the findings of the physical model testing, this paper proposes a new self-starting drainage mechanism. Assuming the groundwater level is greater than the orifice, the drainage system will activate automatically as soon as the water level rises above the permeable pipes’ front end. As soon as flow starts in the permeable pipe, a vacuum is created, which is then transported forward in the soil around the pipe. Therefore, the slope’s stability is anticipated to be enhanced as a unsaturated zone is produced in soil during transmission. The model test findings showed that the hose diameter is a significant element influencing the drainage. Simultaneously avoiding the build-up of air that could disrupt the syphon effect and the need for manual start-up are two issues that this method addresses in comparison to syphon drainage.
