SEEPAGE ANALYSIS OF MATATILA DAM USING SLIDE SOFTWARE

Abstract

Seepage pressure is one of the most important factor that affects the stability of embankment dams. In this study a detailed seepage analysis on Matatila dam, Lalitpur(Uttar Pradesh) is done with the help of Slide software. Seepage discharge through homogenous earthen dam, zoned earthen dam and homogenous earthen dam with a cutoff wall is calculated and a comparison is made among them. It was observed that the zoned earthen dam yields better results when a comparison is made with homogenous earthen dam with a cutoff wall for seepage reduction through downstream sloping face and foundation of the dam. Variation of various parameters such as total head, pressure head, pore pressure, horizontal discharge velocity, vertical discharge velocity, horizontal hydraulic gradient, horizontal permeability and vertical permeability are also shown with the help of figures in the results section.
