Considerations On The Stability Analyses Of Geomembrane Faced Embankment Dams And Slope Optimization - Kızık Dam Case

Abstract

It is not so common in dam engineering to design and construct earthfill dams with waterproof geomembrane liners instead of using clay cores. Since any dam failure cause catasrophic results and disasters over large areas located on the downstream side of the dams, dam design engineers generally hesitate using geomembrane liners wherein any holes on the liners may cause seepage forces within the embankment materials.  Therefore, engineers mostly prefer to use with well known traditional materials such as concrete face, clayfill, and asphalt membrane to provide water tightness for embankment dams. However, in recent years, in the World, there is an attempt to use geomembranes on the upstream faces of embankment dams as water barriers. There are recently some small dams with geomebrane water barriers constructed less than 30 meter heights in Turkey and in the World. In this study, for dam design engineers, it is shown that critical slope loading cases for dam slopes with geomembrane liners are different than those for conventional embankment dams with clay cores. So, this study will provide a technical source and a guide for dam engineers by the way of explaining some important criteriums to analyze and design the slope of the geomembrane faced embankment dams along with Kızık dam.  In addition this study briefly discusses also some other design principles of geomembrane faced dams. Moreover, the study shows how to optimize the outher slopes of geomembrane faced embankment dams in terms of safety and economy.
