It holds on at its base and at its flanks… In other words, a dam is made up of two parts: the artificial dam...

The access tunnels (including the Singe fault zone) contribute about 300 l/min, and the seepage from a sub-horizontal zone into the service tunnel under the silo is about 100 l/min...

... is greater than the dam itself. For earth and rockfill dam founds- tions, the major problems are: the large amount of seepage water, the nonuniformitY of seepage, the existence of probable path of concentrated seepage. These are the key problems concerning the treatment of dam foundation. The col dam...

Furthermore, it must have the impermeability against seepage from the reservoir through the foundation so as to prevent seepage from causing piping of fault material. With these imperatives in mind, the stability of the fractured zone was investigated...
