Right-bank earth dam of the Bratsk hydroelectric station
Conclusions The right-bank earth dam is working satisfactorily, but there are processes which require greater attention.Settlement of the dam for the most part is diminishing, but it has still not ended. Consolidation of the loose layers of the foundation is continuing.The overall seepage regime is stable in time. The piezometric levels and discharges are staying within certain limits at the corresponding UPLs. The levels in the piezometers do not exceed the design lines of seepage. The exception is the discharge in collector drain No. 2, which showed a tendency toward an increase in connection with piping into the gallery at DM 46.The presence of two piping centers in the drainage gallery at DM 30 and DM 46 requires greater attention. The installation of flumes with a sand blanket is stopping piping into the gallery, but is not reducing the gradients of the head at the outlet, i.e., it is localizing the processes but is not eliminating them.The effect of the constantly acting vibration loads on the dam is unclear. This process may lead to consoldiation or liquefaction of the soils, which should be established by constant seismometric observations.
