Liptovska Mara dam

摘要

Foot drain of the Liptovska Mara dam was founded high over the groundwater level. Seepage regime can be analysed only with the help of observation objects on the base of water level and velocity regimes. The dam subsoil was sealed with a short grout curtain that has been completed during reservoir filling and operation of the power project. Its quality has been controlled by water pressure tests; the required criteria were not attained, in spite of that is the curtain efficiency good.
