Investigation on parameters used in warning systems for rain-induced embankment instability
Gallage, Chaminda & Uchimura, Taro (2010) Investigation on parameters used in warning systems for rain-induced embankment instability. In Kwok, Charles (Ed.) Proceedings from the 63rd Canadian Geotechnical Conference (GEO2010), GEO2010 Calgary, Calgary, Alberta, pp. 1025-1031.
A number of instrumented laboratory-scale soil embankment slopes were subjected to artificial rainfall until they failed. The factor of safety of the slope based on real-time measurements of pore-water pressure (suction) and laboratory measured soil properties were calculated as the rainfall progressed. Based on the experiment measurements and slope stability analysis, it was observed that slope displacement measurements can be used to warn the slope failure more accurately. Further, moisture content/pore-water pressure measurements near the toe of the slope and the real-time factor of safety can also be used for prediction of rainfall-induced embankment failures with adequate accuracy.
