Seepage and stability analysis of earth dams

Abstract

In general, all water retaining structures are subjected to seepage through or under their embankments. If the seepage is not controlled, structural failure is certain. The object of this project is to present a review of the seepage problems and stability considerations involved in the analysis of earth dams. It contains a review of the seepage characteristics of soils and their effects on earth embankments. The problem resulting from seepage and different methods for controlling seepage are fully discussed. Because many uncertainties remain, the stability of the embankment must be determined. Four different methods are presented for analysis of earth embankments to determine their factor of safety against stability failure.
