PENGALIRAN PADA INTI BENDUNGAN TIPE URUGAN PADA PENGGENANGAN PERTAMA WADUK

Abstract

The first impoundment on the fill dams can be considered as a critical phase during the lifetime of the dam. The change to the embankment materials, especially on clay core shall be carefully examined. Some dams were ruptured during their first impounding due to the flow through the core. The flow through the core of the dam during the first impounding was considered in the condition of unsaturated.This paper intended to study the literature available regarding the flow through the core of the dam. The factors affecting the flow through the core such as pore pressure parameters, empirical equations governing the flows on the core and volume change will be discussed.
